What qualitys should I look for in a Mustang Mach 1 1969-71?

first let me say i have driven a 71 fastback and i dont liket eh mailslot they call a rear window, and the shape of the quarterpanels kills rearward vision. that said look for cars with little or no rust, and as original as possible re: paint color, wheels, engine, trans, rear end, etc. low mileage cars that have not been raced are also desirable. a car that has never been hit, or one that has been repaired properly is also good. for engine, unless you want a big block, i would look for a 351 powered car as they have the best overall compromise between performance and mileage. any of the 351's is fine, but if you can find one and afford it a 4bbl 351 car is best. trans is your choice, but if you can avoid it stay away from the fmx as there is not much available for it anymore. i like the 70 body best, the 69 next and the 71 wwwwaaaaaaayyyyyyyy down the list.
