You're going to lose. Sorry...
They said the engine and transmission worked great. They didn't say all the headstuds were good, that it didn't have hidden broken bits, etc. "worked great" is a highly suggestion term that does little more than convince one that the car can probably move under its own power.
"The clutch is tight". What the hell does that mean? That it's out of adjustment? That the pivot is seized? It means NOTHING. There is no automotive term other than mis-adjustment that "clutch is tight" means.
They said the power window mechanism worked great. It probably does when you jumper it to a 12 volt source. They made no promises to the rest of the electricals. They did not even say the car would start but that is somewhat implied by "engine and transmission work great."
"Great compression" means nothing. Specific numbers and leak-down tests by a qualified Porsche mechanic DO mean something. The term "great compression" is subjective. Just like my version of a great day might be someone else's cause for hard alcohol and valium. They think they compression is great but there are no quantitive measurements to back that up.
You got hosed. The guy is a disgusting schiester. But you will not win this one. You will only spend more money and personal aggravation chasing this nasty person. I should know... I'm a MOTOR MEISTER victim... This experience is your "motor meister." Lick the wounds, build a good car and NEVER do what was done to you to somebody else.
