sooooo making a Porsce mid engined doesnt make it a porsche?..lol the GT9 is a highly modefied GT3, and the GT3 is a porsche. i like the car dont get me wrong, it doesnt look to bad, but is sounds fkn awesome, but its still a tuned porsche.
The issue is "Is it a Porsche or is it a 9ff?". There are plenty of manufacturers that use someone else's engine. The GT9 obviously uses a bit more than the engine. There is a line (somewhere) that divides tuner from manufacturer. 9ff (with the GT9) is on the manufacturer's side. Different people put the line at different locations, I suppose.
For me, the major chassis changes make it more of a 9ff than a 911. the same could be said for the Ruf CTR3.
Saleen is/was both tuner and manufacturer. The S7's engine is basically a modified 427cid Ford (internally) but no one calls a S7 "just a modified Ford". A Saleen S281 could be called "a modified Ford" because it shares so much with the Mustang, but technically, it's a Saleen since Saleen is legally an OEM.
