As I am writing this now, that auction is at $385.
I don't see a reserve, nor do I see a "Buy It Now."
I am very curious as to what that will finish at.
Somethings to note however:
The seller does not know what car this is for.
He states: "Engine: Toyota Supra 7M-GTE MKIII" yet the engine pictured is a JZ motor.
He also states: "FITS Toyota Supra 1993-98 7MGTE" when in reality, those years fit the 2JZ time period, and the 7M-GTE ended it production by then.
The car's body in the pic is an MKIII though.
Lots of sellers on eBay don't really know these cars.
If that deal doesn't work out for you, I know a guy selling an exhaust manifold.
