I’m considering buying one of a few cars, but I’m not motivated most of all by the model or brand, well only slightly; I like both Mustangs and Camaro. In fact if I were to use my whole available budget I probably would buy something entirely different like a stinger. However because of current market I’m trying to avoid overpaying by getting a cheaper, older used car to use for a year or two until it returns to normal. The ones I’m looking at are all manual transmission v6’s, and asking price ranges between $8-10k an '05 mustang premium with 38k miles, an '08 mustang with 86k miles, and a '10 camaro with 83k miles. From my own experience and bias I would say ford generally is more reliable and inexpensive to maintain/repair, and GM vehicles generally are subpar, but some sources like J.D. Power say that specifically the early model years of the 5th gen camaro are actually pretty reliable.
So, as unbiased as possible, which is the better bet for reliability/ low cost maintenance?
