    Hello everyone! I have owned a 1993 MR2 since 2007. I am the third owner, but the second owner only had it for 1 year and drove it once because he was a truck driver. So it sat in his garage. I'm all about rare and high quality parts. No knock offs or cheap stuff! I say do it right the first...
