I had 70's cars in the following order:
72 Camaro- nice style, terrible motor, trunk would fill up with water, dash electronics fried. ONly had car for 20 months
74 Vega GT station wagon - ordered it from factory, had to be repainted off the truck before taking delivery due to peeling, it got rust holes big as baseballs in fenders. kept it 12 months.
76 Buick Regal - nice looking car, some motor and trans issues, kept it 4 yr. traded it for an 80 Buick Regal DIESEL. That was THE worst ever. Traded it in 6mo for an 80 Mazda 626 and started a decade of buying foreign cars refusing to buy Detroit junk.
The next decade bought various Fiats, Mazdas, Nissans, Audi. All were pretty bad on retrospec so not sure that I accomplished anything buying foreign either!
