I just picked these 2 cars up for dirt cheap the other day. One is a 1965 Mercury 404 comet 2 dr I6 auto w/out title and the other is a 1968 futura 289 c4 car w/clean colorado title. My question is should i combine the 2 to build the comet? or should i just leave them stock and restore? Both are numbers matching. The comet has original keys, owners manual and 45k miles. It also is complete all trim and interior. I belive the only thing missing is the stereo but i'm not even sure if it even came with one. The futura has all its trim but the interior is about a 5-6/10. Both run and drive although the comet is gutless and i'm sure 6600' above sea lvl dont help any. Both have some rust also. Just looking for opinons.
