An6drew;
I'd agree about being cautious with that car, especially because of the rust. Do a search on this BBS for "Rust". About a year ago a poster from Scotland posted pictures of his car after it had been stripped. It's not for the weak of stomach, but it will educate you real quick about the places to look for rust. As far as the chassis being "straight", the only way that you can tell this is by putting it on an alignment machine or by driving it through a puddle. Check the tire tracks and make sure that they track straight and are even. For example a car is not straight if the LF tire tracks inside the LR while the RF tracks outside the RF. (Ask me how I know!)

As far as the MFI backfiring, that is an easy fix, and also potentially a good negotiating point. Fixing it could be a simple is adjusting the overrun switch. If you are interested in buying a car with MFI, read the tech notes here on the Pelican site about MFI. They are THE best source for MFI information short of moving in with the one of the few folks who still rebuilds the system. Working on an MFI is not as bad as people make it out to be. Do a search on this BBS for MFI. The hesitation below 3000 RPM could be MFI or ignition related. It could also just be fouled plugs. The CDI should prevent this, but an MSD ignition I've found to be better still. Above 3000 RPM an MSD works no better or worse then a CDI. I don't think that a backfire while on the hand exhaust is a really big deal in an MFI car.

You mentioned the 915 gear box. That's strange since they were not standard until 1972. What was the sift pattern? R-1/2-3/4-5 or 1-2/3-4/5-R ? The 901/911 transaxles had the former while the 915 had the later. Unless the engine's torque was greater then a 901/911 could handle, I wouldn't necessarily consider a 915 an improvement over a 901/911. But that is just my opinion.

Finally Ruetter didn't build any '69 body shells, not exactly. By this time Porsche had bought out the Ruetter body works and so any "Porsche" bodied cars were most likely built by people who formally worked for Ruetter. It was a "friendly" takeover, so I didn't get the sense that many of the Ruetter people left. I'm sure that Herr Kunz on this BBS may even know some of them! Now Karmann did build some of the 911 bodies. I have one. The quality is comparable to Porsche's inhouse bodies and I've never heard of anyone describing problems associated with them. BTW; Karmann has also built bodies for VW and BMW and the reputation has always been good.
