Dave,
I am tentatively in the market and been researching for a GTP/IMSA/Group C car and thought about this car a couple times. It could bring together my love of De Tomaso and desire to vintage race. Don't take this the wrong way, but I have seen it advertised on various sites anywhere from $199K to $345K all of which IMO is too expensive for a car that needs a race motor and full crack testing.
In comparison I can get a fully restored Le Mans Class winning GTP car running a Cosworth V8 for $200K.
If it becomes more realistically priced I might be interested.... wanna trade?
