I'vr bought many that needed absolutely nothing - and several that needed virtually no repairs for years. My (wife's) is a 2002 Ford Taurus we bought 2 years ago with 58000 km on it. I replaced the tires this spring, as well as the headlights (yellow and crazed) It has 86000km on it now. The heater control had hiccuped twice in the last 2 months so I popped out the mix door servo and re-lubricated it.
My pickup had 308000km on it and I knew it needed a clutch slave cyl when , plus a windsheild.. That was 3 years ago. Only problems since were "U" joints and a cracked hood in the evap system. - has 326,000km on it now - 17 years old next month.
Youngest daughter's old Neon - bought with almost 200,000km on it and in the first 2 years just needed a rad andt brakes. Nothing in the first year.
Wife's '88 Chrysler, bought with 100,000km at 6 years of age - first required repairs were 3 years later when the cat converter plugged - ended up needing cyl heads replaced. 3 years later front suspension work, and when it was 15 years old, the transmission went bad (actually the differential - but inside the transaxle). Sold it in good running condition at 18 years of age - had to put in a steering rack to certify it for sale,240,000km.
The 85 LeBaron before that was the rainy night special - had more rust than I thought and the engine was totally shot - not repairable. Had to put an engine in it. $1000 car, $1000 engine - went 4 years before the body got too rusty to put on the hoist to fix a brake line.
Then there was the $500 Pontiac TransSport - bought with a blown engine. rebuilt engine for $2800. A year later the transmission cost me another $1000.. All kinds of stupid little things on that van - but it WAS a GM. I got what I bought - a pile of headaches - for $500. I think I drove it 7 or 8 years and put $100,000km on it before the rebuilt engine let go.
Years before I bought a 1980 Tercel with 300,000km on it. Mechanically it needed nothing. Several years later I put a new timing belt and clutch in before a long road trip. The clutch was still in good shape, but since I had it out I put in a new disc and bearing.. 6 years or so without any mechanical failures. Just fiberglassed the back fenders. The car was well maintained by myself for the original owner.
