Well I'm pretty sure I'm still gonna roll with it and buy it. I'm from Wisconsin - and unfortunatley nobody here wants to sell their GTP's. I've been looking for about 2 months and this is the best deal I have found. The only reason why I was uneasy about it is the price - not the quality of the car.
I drove it pretty hard yesterday and the tranny showed no signs or issues with it. Also - the guy called again and said he found a switch and is going to replace it for me before I buy it - so that's nice too.
As for the supercharger oil - $125 is a lot. I looked for a write-up on here, but couldn't find one. Anyone want to help me out and throw me a quick write up? If so, I'll pass on the dealership service and do it myself tomorrow. I'm no pro technician - but I know my basics, so a write-up would definitley help.
Thanks again to everyone! I'm glad to finally become a true member of this community!
