slowest, my buddy's 78 mecedes wangon, i know its a bit out of the 30 year requirement, but it runs 24.5 all day long, sad part, he wins at the local track, the ricers cant idle long enough to spot him time lol. its a 3.0L in line 5 with like 89 hp, but lots of torque, it also runs 24.5 with 5 people in the car, it just doesnt care slow is slow for it lol
