The sweetest deal, imo is when you can find a low mileage garage queen at a reasonable price and then turn it into your like new daily driver. Cars and Bids has a sweet MR2 as well as V6 Miata.
Cars & Bids: Auctions of cool modern cars, trucks, and SUVs
Cars & Bids has daily auctions of cool enthusiast vehicles from the 1980s to the 2020s — like Porsche, BMW, Mercedes-Benz, and more.carsandbids.com
As a new auction site, Cars and Bids' following is still growing so there might be less competition or bids per car.
My concern with someone else's garage queen is potential lack of maintenance. Like that one listed has 10k miles, but it's sitting on 14 year old tires.
