1988 Regal promo kit. I saw it on Amazon and couldn't resist. I've added some details and changed the wheels & tyres. More pics here for those who are interested. http://skidsplace.forumotion.co/t4275-88-buick-regal
Hard to believe that G body replacement is nearing 30 years old. It might have technically been an 88 1/2, as RWD G body production ended in Dec 1987
