MSN's Turbo Buick Website! (http://Communities.msn.com/HotAirTurboBuickWebsite)

If you are interested in the '84/'85 Turbo Buicks you can check out our site. Good luck getting involvement from boards dedicated to the "intercooled" side of the house.

If you go to TurboBuicks.com you'll get more chuckles than help.

If you go to TurboBuick.com you'll deal with idiot moderators with chips on their shoulders and loyalties to their advertisers.
(Some day folks will catch a clue)

www.GNTTYpe.org has some interesting information.
