Hmm, not really. It's still such an ideal car, but this has just reminded me it's old and prone to failure. If I replace the torque converter, it's really only the transmission itself and the engine that can throw up big bills. However, the transmission has done ~100k, and the engine 184k - am I stringing the car along past its sell by date? Maybe. Especially maybe as I drive a lot, not in the most sympathetic of manners, and those facts aren't going to change any time soon.
If I were to decide to change, I have the problem of deciding what. I want something faster, more comfortable, better built, newer, more technology and more economical. They, unfortunately, lead to a large price tag, and I don't want to shell out tens of thousands on a car right now. A car that I am considering a bit is an E60 535d. However, that puts my total car ownership cost up to around £1000 pcm, from around £750 pcm with the 530i. Decisions, decisions!
