We bought our 2005 Corolla in 2007. It was a repo with 13,000 miles on it. It is 2012 now and the car has 160,000 miles on it. The car, knock on wood, has had no problems that I can recall except needing usual oil changes, tires and brakes replaced. We also had the serpentine belt replaced when it needed it at about 100,000 miles. The car gets excellent gas mileage, between 30-35 mpg average. We had a problem with the air conditioner about a year ago and then found out that these cars have a cabin air filter behind the glove box. Cleaned dust and leaves out of filter and air works fine again. Does not burn oil. Just a great car. We love our Corolla and have purchased 2 more since.
MPG, reliability, handling, quiet engine, low maintenance. Just overall great car!Drove a friend's Ford recently and could hear and feel the Engine dragging. Was surprised how loud an Engine can be. My sister loved my Toyota so much that she purchased a 2007 right off the lot. No problems with hers either, now 5 years later. She says it's the first car she has ever had that hasn't always been in the shop! So impressed, they bought a Prius afterward!
Can't think of any improvements needed. I am hoping to eventually afford a Prius!
