....I build the Sport Trac Adrenalines and we just started to ship out to dealers last week. The majority of them had window stickers of over 30,000......most around 35,000..........basically the difference between a Adrenalin and a Limited Sport Trac is cosmetic. The front and rear bumpers ( fascias).....the front and rear fenders (there is no wheel lip moldings).....the running boards are painted to match and no roof rails.....the engine is the same...drivetrain the same.....i have a 07 limited 4x4....the adrenalin is an awd or 4x2....the window sticker actually has it listed as a limited sport trac with the 2995 dollar Adrenalin option..........hope this sheds some light...........i'd love for it to have a supercharger cause i think it looks great!
