JMHO......and I ain't one of the more knowledgable Z owners.....but for that $ you can find low milage 90's, 20k miles and under & one owner clean titles, all day long...ya just have to look for them.
Ofcourse if they want to donate the car to ya....well then go for it....otherwise do yourself a favor & keep looking. This is a very good time to be a buyer of ZR-1's.
