Three cars two I didn't own:
1978 Chevrolet Caprice wagon 305 V8/3-speed slush-o-matic
1984 Plymouth Turismo 2.2L 4cyl/5-speed manual
Both were built and designed by people who really didn't have a clue or care. A car is made of many components, but can have design problems, but rarely is the WHOLE car just bad. Both owners seemingly fixed almost the entire car.
These were. Mediocre in almost everyway. Design, fit and finish, build quality, materials, refinement (even for the time), reliability, durability, performance, handling, gas mileage (the Chevrolet was horrible and it did nothing despite a V8), Plymouth was good on gas ~40 mpg. The Plymouth was a uncompetitive for 1984, just they had the US Ford Escort and the GM J-cars as an excuse. It was a bad time in US car industry late 70s to early 80s.
My car is a 1997 BMW M3 3.2L I6/5-speed manual
Great to drive and that's it. Very overengineered. Electrical, suspension, and body hardware regularly and apparaently very common problems. None of the performance stuff, just the basics. One of the most fun cars I've ever driven that's a sedan, not the fastest, but fun. Moneypit.
