Cool find: I have number 8 of 20 Solstice Hardtops made by EDAG.?
Far as I know EDAG has never disclosed number of tops produced. All I have is an estimate by Peter of RevengeDesigns that RD installed around 40 hardtops and had another 50 available at heavy discount pricing of $1K (with some paying as low as 5-$600). Regardless, that's a substantial savings over the initial price of $2500. It's possible the seller paid original pricing. Plus it does appear to be a complete kit, and as far as I can remember RD wasn't able to offer complete kits during the end of their EDAG hardtop liquidation.
