Having a hard time believing this as well. Roadster owners are willing to pay up to $20k, that's more than most entire kit cars.
I don't have a roadster, but with all the nonsense about these aftermarket tops with the crazy costs and the unavailability, why isn't someone getting with one of these home fiberglass kit car builders?
Those dudes can make make anything out of fiberglass. Heck they make entire Murcielagos from a bucket of resin and some fiberglass mat that fits on some ridiculous chassis like a Fiero, and then they sell the whole thing for $10K on eBay.
How much could they possibly charge you to make a removable top? I am thinking that they would be happy with $20 plus the privilege to rub themselves against your real Murci. But what the heck, make their day and give them a $1000.
