I recently posted a question about whether I should add a hardtop to my 255, which is on order for Spring delivery. In response to overwhelming endorsements of the value of the hardtop I asked my dealer about the cost. It turns out that a GW factory installed hardtop is around 12K. I have asked GW why they cost so much and have gotten no answer. It strikes me as outrageously expensive. Does any :huh body know why these things are so expensive, and has anybody had any experience with aftermarket installed hardtops?
