  Could have really been great - 1999 Cadillac Deville
  By SnoopDeville - October 6 - 2:40 pm

  Good: 1. It was pretty fast for such a big car (Used to laugh at civic SIs) 2. Got pretty good MPG at 23MPG all around and over 30MPG on the highway if you kept your foot out of it 3. The bench seats are awesome 4. Enough room to fit all your friends in the back seat.. (And it they pissed you off, they could all fit in the trunk on the way back) 5. It gives you a very protected safe feeling 6. Hitting huge pot-holes feels like running over gravel Now.. Why it got such a bad number of stars.. 1. I bought the car used it had 68K miles on it. 2. The car started to have over heating issues.. I replaced the radiator with a triple core aluminum dragster radiator off of a chevy dragster. The Thermostat didnt circulate the coolant until it was too late, which at 236 degrees for the system to start to circulate is what caused the issues with the head gaskets on these cars. Pulling the Thermostat and buying one made for a different engine (shortstar) and using that one with a bypass on the two 26K CFM fans cured the overheating issues. (NOTE: you cant do the head-gaskets on the 98-02 Northstar, since the head is structural and the engine will warp when you pull the heads.. Entire engine must be replaced) 3. When it rained the tail lights didnt work 4. The alarm would randomly go off. 5. Replaced the power window motors with other Cadillac ones, Twice, before using Toyota Camry ones modified to work in the caddy frames. 6. Dealership wanted to charge me 150.00 for Windshield washer blades.. (Are they high?) 7. Exhaust rotted off the bottom of the car (Stainless isnt a choice on a 40+K dollar car?) (No matter though some Super40 flowmasters and two 3-1/2in chrome tips sounded great) 8. quality of the interior materials are made from cheaper plastics than rubber maid garbage cans. 9. car had electrical issues, and eventually randomly caught fire. (Ironically after the fire department put it out, all it took was some new ignition wires and it started right back up. ) Verdict: These cars can be fantastic cars for people who have some automotive repair skills, they are also fantastic cars for people who live in areas where there isnt heavy traffic. If you live in the middle of mid-town Manhattan, look for a Fleetwood, which while these look alike the fleetwood LT1 is a much better engine. If you however are stuck on one of these for whatever reason.. Keep an open eye for coolant leaks, oil leaks, transmission slips, and mostly overheating. Have the person start and run the car, wait for the coolant fans to kick in before you buy one. Most of these cars are marketed at needing a "head gasket" however, you cant replace the head gasket on the 98-00 Northstar, the head is a structural part, and pulling it will warp the block, which will result in leaking head gaskets as well as other issues. If you find one without the over heating issue, replace the thermostat with a lower temp thermostat immediately, and replace the coolant fan switch with a manual, or adjustable one, choosing to kick on the fans at a much cooler temp (201 vs 236). Doing this will enable you to have a car that will get you around at a very low price.

  Good car when new, but its falling apart - 1999 Cadillac Deville
  By danieluga - June 19 - 9:52 pm

  Bought the car new in November 1998. It was great for about 7 years/50,000 miles then started leaking coolant. 16.5 years/135,000 miles into its life it overheats going 15 miles down the road. Happily traded it in a few days ago for a new Prius. Cadillacs seem to be great when new but dont stick around for the duration. Northstar engines are economical and powerful but have issues...done with Cadillac

  1999 Cadillac DElegance - 1999 Cadillac Deville
  By robooo - February 21 - 5:32 pm

  Bought in 2011 with 92k miles, had to have new front struts put on by dealer. Now at 120k miles, I have had to put new radiator fans, new radiator as fans ruined the radiator, torque converter, TPS sensor, a blower motor which took a week to get a 5 bolt since most are 3 bolt and just recently a water pump. All are expensive to fix. Good running car, but like everyone says, they can be expensive to fix. If you buy one used, make sure you like the car and have some money set aside to fix them. Watch your selling price, weak resale value for a Cadillac. Heated seats dont work. Had to convert rear suspension

  What a deal! - 1999 Cadillac Deville
  By albee213 - December 20 - 8:40 pm

  I have two Deville Delegance Cadillacs, one a 98 and the other a 99. I purchased the 99 with 89k and owner though engine head gasket was blown, tested engine, nothing wrong but the thermostat was rusted shut. New thermo, flush and coolant and it runs perfect, better than my 98 and it only has 65k, I can not explain it, the 99 engine is smoother and more powerful. I would recomend these cars to only someone who is willing to spend money if something goes wrong, its worth every penny when you compare it to modern cars at 50 plus thousand dollars.

  I Feel Lucky - 1999 Cadillac Deville
  By junebreeze - July 10 - 5:13 pm

  I bought this car because it had low milege and I was able to buy it very cheap because it was already 11 years old. I am sooo glad I found it. It rides like a new one. I have had it 2 years and I know it only has 60,000 miles on it but I can not say one thing negative about it. The power is wonderful, the traction is tops. The gas milege isnt even bad for its model and size. The paint job is a beaut. It gleams! Thank you Cadillac!

  Snowplow Caddy - 1999 Cadillac Deville
  By Caino - October 25 - 2:00 am

  I drive 80 miles round trip daily to work. I live in northern Maine, 2 hours north of Bangor, me. Ive had to plow my way out of my driveway, and out of 2 other roads (2 miles) before I got to main road, at 3:30am. Sometimes i had to plow the main road for miles before it was plowed going through 1 to 2 ft. Drifts. That car never faltered once! I driven through countless blizzards! That car is the most reliable car Ive ever driven. The front wheel drive along with the heavy v8 northstar engine gave the car unbelievable traction. I never worried about being stuck in snow or heavy slush. It was safe consistent and dependable. If I hit a moose it would land on the hood and not on me. Car is bigger than moose!

  Whos your Caddy? - 1999 Cadillac Deville
  By Richsap - July 19 - 9:47 pm

  This is the 3rd pre-owned Cadillac Ive had the pleasure to purchase, and they just keep getting better. I traded up from a 95 Concours to a 99 DeVille and now to a 99 Concours. As with most vehicles, the older the car the more likely issues come up, and Cadillacs are no exception. The 95 was on the verge of becoming unreliable, which I attribute to a faulty fuel injector and a starter that had an intermittent issue and would on occasion not function. The 99 Deville was (is) a beauty, until it got hit by an idiot running a red light and totaled by the insurance company. I used the funds to purchase the 99 Concours, and after replacing a malfunctioning alternator it runs & drives like new

  Dream ride - 1999 Cadillac Deville
  By midway - May 8 - 9:09 pm

  Have owned for 10 yrs, now at 100,000 miles it still runs and looks like new. Never had a major issue with this car, its never left me stranded and always starts right up. Everything still works! Cant understand why everyone knocks American car quality!
