I don't want to start a riot when I say this, but most of the conversions I've seen for sale are within one or two years of being done.
Two theories......................
1. Met the challenge, been there done that bored with it - flipping it.
2. Does not have the feel of an early car, nor the engineering packaged balance of a later car and is a disapointment over time.
I'd love to be that disapointed.
