What was the worst car you have ever owned?
My would have to be a tie between a 90 Dodge Shadow 2.5L and a 98 Honda Civic. The Shadow because it had peeling paint, overheating, and rear brakes that were non-functional. The Civic because it was such a pile of shit. 2 trannys in 4 months. More rattles than my old 78 Camaro. Odd engine noises and misc bits braking off (like the door handles).
My best car from reliability point was my old Dodge van. Had the 360 V8 held together with oil but never needed any repairs. Honorable mention to my Camaro too.
