Overview & Reviews

BMW doesn't usually do retro, but the BMW 1 Series, a spiritual successor to the iconic 2002 coupe, comes pretty close. Produced for the 2008-'13 model years, the 1 Series coupe and convertible were meant to evoke the same passion that the 2002 did. As the company's entry-level model for those years, the 1 Series offers true BMW performance at a surprisingly affordable price. Its styling may be an acquired taste, but the 1 Series retains much of its original appeal today as one of the best values on the used-car market.

Note that the 1 Series' successor, the 2 Series, is reviewed separately, as is the rare 1 Series M coupe.

Used BMW 1 Series Models
The BMW 1 Series debuted for the 2008 model year and ran through 2013. It was available as either a two-door coupe or a convertible with a power-operated fabric roof that folds underneath a hard tonneau cover.

Although it was the company's least expensive model at the time, the rear-wheel-drive 1 Series had no shortage of motivation under the hood. The 128i came with a naturally aspirated 3.0-liter inline-6 producing 230 horsepower, while the 135i stepped up to a turbocharged 3.0-liter inline-6 with 300 hp. The 135is packed an even higher-output version of the turbo-6 (320 hp).

Standard features on the base-model 128i included 17-inch alloy wheels, premium vinyl upholstery and a 10-speaker sound system. The 135i was differentiated by its turbo engine, 18-inch wheels, xenon headlights, slightly different front and rear fascias and a sport-tuned suspension. Some of these items were also available on the 128i. The 135is was sold for 2013 only with a bit more power than the regular 135i, plus standard sport seats and some aesthetic tweaks.

All 1 Series models offered a bevy of luxurious options familiar from BMW's pricier offerings, including leather upholstery (with sun-reflective surfaces on the convertible), the iDrive infotainment system with navigation, keyless ignition and entry and premium audio.

The 1 Series saw a few powertrain changes during its run. Initially, the 135i's engine employed twin turbochargers and was a bit less fuel-efficient, but the 2011-'13 models (including the 135is) switched to a newer design with a single turbocharger. Those models also received an optional seven-speed dual-clutch automated manual transmission known as DCT, whereas the previous 135i -- and all years of the 128i -- offered a conventional six-speed automatic. A six-speed manual transmission was standard on every 1 Series.

In reviews, we found the 1 Series' handling to be simply superb. Precise steering combined with a well-balanced chassis make both coupe and convertible feel right at home on a coastal freeway or a serpentine mountain road. Body roll is minimal, and the overall dynamics on models fitted with the Sport package will win approval from all but the most hard-core enthusiast drivers.

The 1 Series' turbocharged engines are incredibly versatile and offer an intense slug of power and acceleration with hardly any turbo lag, though the response of the gas pedal can be less than immediate. An overlooked gem is the 128i's non-turbocharged inline-6, which delivers smooth yet potent thrust in classic BMW fashion. This engine may be of particular interest because the 128i's replacement, the 228i, employs a turbocharged four-cylinder, so the naturally aspirated inline-6 marks the end of an era. But no matter which 1 Series you choose, you're in for a good time.

Interior materials are a step down from other BMWs, but the overall effect is still pleasingly upscale. The rear seat is strictly for two, and how often it gets used will depend on how large and how forgiving potential rear passengers are. There's not a lot of space back there, so it's almost better to consider the 1 as having a sports car-like 2+2 seating arrangement -- especially the convertible.

Powertrains aside, the 1 Series saw mostly minor changes during its production run. A new iDrive system debuted for 2009 with significant upgrades; we do not recommend the inferior iDrive interface offered in first-year (2008) models. A sunroof was standard on 128i coupes until 2010, while the 2012 lineup was treated to minor exterior styling revisions and refinished interior controls. The 135is headlined the 1 Series' farewell tour for 2013.

Although it was new to the North American market for 2008, the 1 Series actually debuted for the European market in 2004 as a hatchback.

  Excellent car - mixed bag transmission - 2013 BMW 1-Series
  By kjgood - January 3 - 10:44 am

  This is my second 135i convertible, and I have over 20k on this car at the time of this review. I was somewhat reluctant to order it with the then-new-to-the-135 7-speed dual-clutch transmission instead of the manual, but I was persuaded by the thought of the lightning-fast shifts and the advantage of being able to select between auto and manual modes. The reality is that in manual mode, and even auto mode for fast acceleration, the transmission is brilliant. But in stop-start, mundane "through the neighborhood" use (where you just want to leave it in auto-mode), the transmission is hesitant, clunky and confused. In other words, where you most want it to be an automatic, it is wanting.

  Fair Car Needs Modification to Be Good - 2013 BMW 1-Series
  By rudycassap - July 21 - 11:24 am

  After coming out of a Scion FR-S, I felt the suspension in the 128i M Sport to still be too soft and sloppy (lots of roll and bounce). Car improved with a Dinan Stage 1 suspension (Konis and shorter springs). Then ditched the Goodyear Eagel Run on Flat tires for Bridgestone Potenza S-04 summer tires and now it is comfortable, sporty, and actually quieter in the cabin. Car has adequate power but could use a little more horsepower for freeway passing - I guess they could not step all over the 135i. Best part is the silky smooth Inline 6 cylinder engine without the turbo issues that plague many BMWs. Cabin and trunk are a little small, but enthusiasts actually love this chassis more than M3.

  Last of N/A Inline Sixes - 2013 BMW 1-Series
  By 71boattail - February 21 - 12:23 pm

  After test driving many coupes in the $30-$40K range, I drove the 128i on a whim thinking I would check it off the list and move on. After driving it however, I pulled out the checkbook. There are cars with more power and better styling, but I couldnt find any that had the combination of performance, handling and quality for the money.

  Exactly what I have been looking for! - 2011 BMW 1-Series
  By bwschubert - February 20 - 3:05 pm

  I have been searching for a RWD convertible with a manual transmission for some time now and while test driving all the usual suspects in the same price range (new and used) my 128i was the obvious choice. I wouldnt mind a 135 for the significantly increased grunt, but there was no such car available- either new and too expensive or used and too old and out of warranty. Nevertheless the linearity of the naturally aspirated I-6 makes running up to the 7000rpm redline a pleasure, especially with the top down. While true value is debatable (I dont know if I could ever justify the full sticker price of a new one) the build quality, ergonomics and all around driving experience is worth it to me

  135i is Fun to Driive but needs rear tires annually - 2008 BMW 1-Series
  By eric146 - January 20 - 8:39 pm

  This car is a true joy to drive but, the need for Z rated tires and the cost makes this car impractical to be your only vehicle. This vehicle has needed new front tires every two years (25000 miles) and needed rear tires about every year (12000 miles). I finally had enough of the tires wearing out and I choose another vehicle. If you want a fun car, this is it, but beware you will be spending between $375 for Hankooks or $1000 for Run Flats every year. Then do not forget about the Premium Unleaded fuel requirement.

  Great drive, good looks, high maintenance - 2008 BMW 1-Series
  By darthbimmer - August 25 - 10:02 am

  When it was time to sell my beloved 98 M3 convertible I looked at the 2012 3s. Too big and bloated and cluttered with expensive, distracting technology. The 1 series is the spiritual successor to the older 3. Slightly smaller back seat and trunk, but closer in size and with a clean, driving-focused dashboard. We picked one up used with low miles and original warranty still remaining-- a good thing because we have had to use it a lot! We test drove a 128 but felt it was underpowered. The 135 was obviously more expensive but we fell in love the first time we pressed the pedal to the carpet. This car is stupid fast. In a dark color and especially with the top down it looks great.

  First BMW - 2011 BMW 1-Series
  By pleng - June 17 - 8:41 am

  I was looking for a fun car with a convertible top and the 128 was just right. Luckily found a certified 2011 with only 14K miles and got the price break and power train warranty to 100K. A key factor was trunk space since I plan on using the car for trips in my retirement. It will hold a 25 inch roller bag flat and a 22 on its side, and even more in the back seat - great for such a small car I am an engineer and I am impressed with the build quality of this least expensive BMW.

  Like a 4-seat Miata...Fun Fun Fun - 2011 BMW 1-Series
  By socalh2oskier - February 18 - 6:26 pm

  My 2011 128i Convertible has 8,000 miles with nary a problem. Changed the run-flats to Contintental DWS regular tires the first week and it was like driving a completely different car--much better ride. Comfortable seats and just a blast to drive. In some ways better than the 3 series--top down at least you have some useable trunk space with the 128. Almost went for the 135, but Im happy with the power of the 128--engine sometimes lugs a bit taking off, but slap the transmission over to sport mode and it compensates and puts you into the sweet spot of the torque curve and takes care of the issue. Nimble handling. One of the most fun cars Ive ever had.

  I love the 135i - 2008 BMW 1-Series
  By Jorge - December 3 - 2:00 am

  Ive been driving the car for more than 22,000 miles now and I think I can have some comments: 1. I had the usual problems: The HPFP, the bluetooth firmware upgrade, all the tails lights failing and the safety recall for the seat belts. 2. The run flats awful, replaced them with Michellin A/S now and rides much better 3. Gas mileages is not great. The car has been problem free for the last 5,000 miles and I personally think there is NO perfect car, I was lucky that BMW Charlottesville has been ver professional and helped me all the time when I faced problems. However, if you love cars, this is the one! Test drive one and see for yourself.

  Think hard before you buy - 2011 BMW 1-Series
  By Oklahoma BMW Owner - December 1 - 2:00 am

  I bought a 1 series a few months ago. Very unhappy with Jackie Cooper BMW in Edmond OK. Poor service after the sale. It is like they forget you exist. Also financed through BMW Financial and they have a horrible website. Being unhappy with the car I considered trading and it lost $10,000 in a few months. It is still like new and a 2011 model and still lost $10,000. CRAZY! I will never buy another BMW.
