Double Personality, AKA trading spaces Options

[Gunn1]

This is a great place to hang out and just read through all the Forum Posts. I cannot imagine the trial and error a guy would have to go through on his own without this site and its helpful members.

With all of the 914 builders/owners out there that have more than one car in their arsenal this question must have been asked before.

Scenario=
Car One has a clear title, many desirable options and is mechanically sound. the only problem ...car one is a rust bucket and cannot be made whole.

The second Car has basically no mechanics in it, for all intents and purposes it is a complete tub but with no rust. car Two also has no title (Bill of sale).

Question = How in the above Scenario would you be able to combine the best in both of the cars and end up with a nice car? Obviously the mechanics and all the other good stuff would be switched over to the car with the good tub, but then you would have a nice car without a title.... Any pointers, advise?

Thanks
