I have had the Trebeca for a couple of months now and we are thrilled with it. I have two other Subi's (92 Legacy and a 94 Turbo sport sedan) that I just can'tpart with cause they won't die. I have done most of the maintainece myself over the years. Anyway, the plugs in the Trebeca are along the frame (I think) and would be/could be a difficust task for the do it your selfer. Any body done this yet.
