I don’t have specific suggestions, but rather something to look for when shopping for cars. And it’s something that people who aren’t gearheads or mechanically inclined can do.

If you are worried about the engine in a potential automobile purchase being troublesome or not, look for a vehicle that uses an engine that’s used in multiple other things. There’s a Toyota V8 that’s used in trucks, luxury cars, forklifts, and even small aircraft, and it’s a decent engine. The Ford 3.7 is used in F150s, Mustangs, generators, and other equipment. (Although I’d avoid this one in a front wheel drive car)

Past examples would be the 300 I-6 that Ford made for decades, which was used in trucks, boats, tractors, forklifts, generators, and various types of farm equipment. When a manufacturer makes an engine that will be sold to other companies to be installed in their equipment, they seem to take more time to make it less terrible.
