Re: question about this car
Depends what you want to do with the car. Do you know someone who can fix the engine? Do they live near you? Across the U.S.? Will they be able to start on the project next week? Next month?
The facts are it's a heavily modified, older NSX in need of an engine rebuild. To some, that's great news, to others it could be a nightmare. I personally with FI background and solid mechanical knowledge think that low 20's for that car is a very fair price. I wouldn't call it "insanely low" simply because A) it would already be sold B) you have to factor in the stress/time/etc. involved in taking on a project***, not a well running machine.
That's probably a negative view of the situation to many, but if that wasn't the case, the car we are talking about would already have a new owner wouldn't it?
