I personally was blown away by the $100,000 appraised value as that seems to be a good bit higher than most Roadsters are selling for. That said your car looks awesome and you have taken good care of it. Would you mind sharing the mileage and CAC or the Ideal miles it charges to on a standard charge? You did well as it appears you timed the market well. And what an awesome plug to have your car featured on Jay Leno's garage.
Yeah, I thought it was a bit high as well, but hey you never know. I mean I don't think I have lost much at all in 7 years of ownership - paid $70K. So they definitely have not depreciated as much recently compared to most other cars, so the rarity is helping.
I have 34,000 miles and the CAC is 141.
