My son will soon be 16 and I am thinking of trying to buy a BRAT a restore it, as we are a family of Subaru lovers (1-outback, 1-legacy, 1-impreza). Since he's just learning would I be able to find one with an automatic transmission? What else do I look for? Also, is there a reputable place or a good source where I might find one? Thanks in advance for all help. am
