I've looked at several sites that offer older japaneese cars over the years, mostly Bring a Trailer. I tend to stay away from Facebook Marketplace and Craigslist as there are too many stories of fraud.
I definitely wanted the white with tan, 5-speed combo. Not compromising on condition either, this car had only 56k miles and was well cared for, always garaged and not modified.
I just stumbled upon the Mecum auction at the right time so I took my chances. I didn't think it would go as high as it did, but I knew finding another would be difficult.
No buyers remorse here, I've had money put away for a while, so no big deal.
