Hi, I'm about to purchase a 1990 Toyota Dolphin 21 ft auto transmission V6 3.0 efi with 26,000 miles on it. The Dolphin is immaculate, I'm just concerned about the engine, I've heard not so good stuff about the V6 3.0 and was wondering if anyone had this motor? Any problems? What you think about the purchase? I'd appreciate all input. Thank you
