1993 Lexus SC400 Reviews

bought an sc400 right after graduating high school, this is my first car and I love it, im keeping this car 4 a while
I'm on my 2nd SC and have also had a '98 GS400. Fabulous cars - my '92 SC400 with 247K miles didn't run much different than when I got it with 106K. My '98 GS400 probably saved my life in a crash and now I have a '93 SC400. Love 'em!!
