What is it that makes the 'roadster' of lesser quality, Jim? Is it the thickness of the plating? Propensity to scratch or pit? The transmission? Something else entirely?
If you still have an example of each kit, it would be really nice to see a product comparison in the new 'product review' subforum. I know a lot of us were wondering about this very question.
I'm sure that Docstram can help you with the review, if you need it.
