Hey Whats up Tom. I got some good news for both of us, I recently just bought this mustang baseball card off ebay since its one of the only things about california edition 5.0s that i could find. Just like yourself ive been on the hunt trying to figure out if my 89 California edition is real. I commented on your post a while back telling the story of how my dad drove one of these brand new from sears point when they were released, with 0 miles on it, pretty cool. Well for a while all I've had was his word, but i just bought this baseball card off of ebay that says " In a stunt reminiscent of the special 'DriveAway' of Twister Specials at Kansas city international raceway in 1969, Steve Saleen and Saleen Autosport BUILT 50 SPECIAL CALIFORNIA SALEEN MUSTANGS for a their own unique 'drive away' from the Motorcraft NHRA Nationals on July 29th and 20th of 1989. In a press release for 'The California Edition' Mustang, Saleen Autosports announced: "Anaheim, Ca, August 1, 1989... Saleen Autosport in conjunction with Ford Motor Company, San Jose District office, recently showcased the Saleen Autosport 'California Edition' Mustang Gt at Sears Point International Raceway, in Sonoma, California. These California GTs were very reminiscent of the 1968 California Special Mustang. these cars were not full Saleens, but came withe the complete Racecraft Suspension featuring Monroe Formula GP shocks and struts, customized American Racing wheels, and General XP 2000V high performance tires." So there it is, proof that the California 89 and 90 mustangs are real and legit. here is a picture of the baseball card i bought off ebay
