At $12,000 or less on eBay, you could pick up this Toyota MR2 turned Porsche Carrera GT. This kit “is mounted on a salvage-title 2003 Toyota MR2 Spyder with a modest 138 HP 1.8-liter four-banger.” Auction page. Click here for first picture in gallery.
For that kind of money, you could get a nice, honest MR2 Spyder…that hasn’t been in an accident. Or if you really just want a cheap mid-engined Porsche, you could buy a decent first-generation Boxster.
