Re: Prospective first-time owner with some questions...
Get the clutch checked out. If it's good the price is reasonable.
You can throw another 50 horses into it for satisfying acceleration.
The 6spd will benifit with a Sprint Booster as well (about $350 from China last I checked).
Welcome to the forum and have some fun.
P.S. Lose the Jag's before they break you (my .02).
