Ive been doing some research and the GTP and CTSV have almost the same dimensions. I want my GTP to be a rwd, manual V8 like they should have built it, so this seems to be the easiest option. I know itll cost a bit so money is already considered. I talked to one shop already and they said it would cost between 20-30k for having to redo the whole underframe and chassis. I feel like if I got a wrecked CTS, made sure the chassis was straight and fit it to work on the GTP it would be a lot cheaper. Any suggestions?
