I know it was talked about the 255 HP engine, dual exhaust (in lower rear fascia), 150mph speedo, 18in wheels, and lowered body (1/2 inch). But the 300M Special also got HID headlights! That would be awesome if we could fit them in the Treps. Anyway, just wanted to post this information incase anybody missed the article on caranddriver.com (also to note, "performance tuned autostick" whatever that is, 3.89 ratio gearing, higher performance brakes, firm strut damping, tall rear jounce bumpers, 17:1 ratio firm-feel steering gear).
