I'll withhold my own opinion on value because I want to hear what you guys think. I really like the mid year Carrera's and in particular love the color on this car. The car has non-original drivetrain, suspension, instrumentation, bodywork (tail), etc. Thoughts on how those modifications affect the market value of this particular car?
