The 1985 Toyota Xtra Cab SR5 Pickup 4x4. This particular model is termed “The Unicorn” by enthusiasts because of its rarity as the only crossover production year with it being the last year of the straight axle and the first year of electronic fuel injection. It points to a very specific time in automotive history and was immortalized as Marty McFly’s dream truck in the Back to the Future trilogy.
