I know Tom casually, and have been to parties at the “cuda lounge” a few times, but don’t consider myself to have any inside information on his cars.
However, I think he bought it in the late 90s and the price if memory serves was $350,000. I believe the car has been “refreshed” over the years, but I don’t think it’s been through anything approaching a ground up restoration. I doubt he has even $500,000 tied up in the car at this point, so he’s not at risk of ever losing any money on it if it does sell!
