  Got Chevy! - 2003 Chevrolet Impala
  By richard - December 11 - 4:13 pm

  I have a 2003 Chevy Impala which was my company car. I was able to purchase it after the lease ended. It was well maintained per company policy. It had high mileage due to my driving it for business. Because it had no real issues I felt it would be a good buy in 2006 with 72500 miles on it. I have not been disappointed. Its real value is it is paid for. Now that I am retired it is used as a second car. I put on a few thousand miles a year just doing local trips to the store etc. Hope to keep it for many more years. It is the best american car I have owned.

  11 years and still going - 2003 Chevrolet Impala
  By cdnbrian - October 21 - 8:51 pm

  I have had this car since new almost 11 years ago. I have not replaced any major components on this car in over 300,000 km. I have the full original exhaust system. In the past 20,00 km I replaced the wheel bearings and CV shaft. The car still runs like new. I have put paint on the hood and trunk to correct rust but then this car has never seen wax. I had a 93 Lumina and a (8 Lumina before this. In total the 3 chevs have gone a million km. I guess Ill buy another Impala. My son is looking forward to taking this car. Pretty dependable as well as economical.

  Over all Its been a good car. - 2003 Chevrolet Impala
  By bedog - January 16 - 9:03 pm

  I bought this car with 40,000 miles on it. Around 70,000 miles I had to replace my intake manifold gasket. I took it to a mechanic, not the dealership. He installed a quality after market gasket. I had brake rotor issues with this car until I did the brakes myself. I replaced the rotors with quality after market. The wheel lugs need to be torqued to proper specs, this will prolong rotor life. You need to flush and fill the radiator every 1 or 2 years despite dexcool specs. I keep it very clean. This car requires regular oil changes and cooling flushes. Synthetic oil and regular cooling flushes will keep it going. By using synthetic oil you dont need to change every 3K. Let the sensor work.

  Overall a Good Buy - 2003 Chevrolet Impala
  By jon_l - March 21 - 1:43 pm

  Bought my 2003 Impala LS second hand with 93,000 miles for my first car. Ran great for a good while but just had to get the catalytic converter replaced at 102,000 miles, Brake Controller Module Replaced, and my Idle Control Valve replaced, costing me all together $1,200. Despite those issues Ive had no other issues I love my car. It rides real smooth and has some nice power. Has great gas mileage on the highway. This is really the last stylish model before the new Impalas went out. The interior is very nice and there is plenty of room for 5 people to fit comfortably inside. Currently at 104,500 miles and the car is still running great!

  6 Years Later - 2003 Chevrolet Impala
  By v_nick - January 3 - 9:55 pm

  I originally wrote a review in 9/2006 shortly after purchasing the car pre-owned. As we approach the sixth anniversary of purchase, we are delighted to report that this has been the best sedan we have owned! In our entire ownership, we have replaced a relay fuse ($50), a manifold gasket ($300) and a wheel bearing ($225). We finally replaced the original tires and breaks a little more than a year ago. Speaking of tires, my earlier review spoke of front end road noise. This disappeared with new tires. The car was originally equipped with cheap Uniroyals. The car still looks great, and runs and runs and runs! It replaced a Nissan which we purchased new & was totally unreliable.

  Buyer Beware - 2003 Chevrolet Impala
  By zabora - December 16 - 5:57 pm

  Bought my 2003 impala from a reputable dealer with only 41000 miles on it. Originally bought for my wife as a family car, but it has been so unreliable that she wont drive it anymore. It has been absolute trouble since I bought it. First the intake manifold gasket went. Then, the electronics stopped working properly. No signal, no heat control, no air control. All failed at different times. Then the front end started having problems. Tie Rods, Rotors, and now finally today, the steering rack. Completely failed going down the road. Could not power steer at all. I have always been a chevy man, and have lived with typical chevty problems but no more. This is my last car from them.

  Love my Impala! - 2003 Chevrolet Impala
  By Nicole H. - September 1 - 1:19 pm

  I researched a lot before purchasing the impala, comparing to Dodge Intrepid and Nissan Maxima. Loved the impala because was midsized car and could fit 6 people comfortably. Including an adult male in backseat comfortably. Also a great price with great mileage per gallon. Perfect car for starting family and working a distance from home.

  My family has always been a Chevy patron. I liked the looks, drive and amenities of my Impala, but in the last 2 years I have had to replace the catalytic converter$739, the solenoid $875(when I took it to the transmission dealer they had been told by the GM company to start carrying this part as it was defective) the intake manifold ($783)wheel bearing, I will never purchase another GM car.

  This Car is Junk - 2003 Chevrolet Impala
  By Jon - July 27 - 1:46 pm

  Please do not buy this car. GM has gotten so bad, everything they put out is junk. bought the car with 80K, and put 25K on in the last 2 years. replaced brakes and rotors, no biggie, that was easy. car hit 100K and dash board lights lit up like a Christmas tree. ABS and Trac Control Failed, module failed, repalcement cost $2,700 for parts. So that hasnt been done, no more trac control or ABS for me. Had the headlights go out once on a sharp curve, that was nice. the radio light flashed at me, which is a pain at night. in the day you cant read the odometer or radio lights. now the AC blower motor doesnt work all the time. have to shut the car off and restart. this car is junk.
