TWIN TURBO. This is NOT a factory stock car. It has been extensively modified, so disregard the lame price that Kelley Blue Book suggests. Its a 1995 Buick Riviera with 3800 V6, twin 38mm Garrett turbochargers, and an extra-large Behr intercooler. New tires, new windshield, new intake gaskets, rebuilt automatic transmission with shift kit. Too many other new parts to list. IT NEEDS NOTHING. Car weighs 3150 lbs. ... it has been lightened by 650 lbs. $5500 or best offer. Please send me a message through Craigslist. Thanks for looking.Key words Grand National, GNX, Mustang, Camaro, Challenger, Charger, 3000 GT, WRX, STi, Evo, 300ZX, GTP, turbo, twin turbo.
