I'm currently looking into purchasing a FD. I'd like to start off by saying that I am mechanically knowledgable except for rotary engines. I understand these cars are old, and with any car that gets old and used, parts wear and/or fail. I've been reading a lot of testimonials from FD owners about its reliability. My question is, with all said parts having been replaced, rebuilt, etc. how reliable has your FD become? Let me rephrase this question if it doesn't make sense. After diagnosing the problem with your FD's, whether it was the turbos, engine, transmission, etc. having done repairs and replaced with properly functioning parts, would u still need to worry about the FD's reliability? Was the car poorly engineered to the point where even with new working parts that it could still become unreliable within a short time span? I have no problem maintaining this delicate car, but from reading some posts on this forum it almost sounds as if ALL FD's are 100% guarenteed to fail constantly..
