Well, we didn't sell ours, but we just bought one. Paid $58k at a dealer for an '18 A10 with 2700 miles. Every option except sunroof.
Interesting that we're going opposite directions. We made the jump to the ZL1 to have all the modern luxuries with ludicrous speed and outstanding track capability, and still have a factory warranty. Ours will only get tracked a few times a year, as we have a dedicated track car (Miata) that gets the hard core use. Consumables are a
lot cheaper...
