My 03 Cavalier
I have about 170K miles. Original owner since 03.For me it's been a decent car overall. Good auto trans. Good engine(change the oil).
I've run M1 5w30 oil since birth.-Doesn't leak any fluids,uses a a QTof oil every 3k miles. Since about 150k marker, I've redone all the brakes and new hardware-rotors, drums, brake kits etc., alternator, starter, KYB struts, sway bar links and frame bushings, control arms w/ball joints, outer tie rods, new 70k Hanook tires. plugs, Diehard gold battery, from what I can remember.
Need to replace two inner door lock sets. Parts are easy to get and are reasonable. If your a good shade tree mechanic, this car is easy to work on and a keeper. From here on in, for the next few more years, I expect a durable, reliable, start anytime car. There is a little bit of rust which I'll take care of in the spring. Oh, I did use POR-15 on the brakes, trans and fuel lines underneath the car where needed.
30+ MPG. The million mile K&N filter I swapped out and synthetic oil gets me on average an extra 2 mpg.
