Hi, I'm hoping to purchase my first BMW, but wasn't sure if it was worth the price. It's a '95 740iL with 140k miles. The dealer's asking price is $9995. Everything seems to be in great condition, but the fact that the original nikasil engine was never replaced and that it is at such a high milage are concerns for me. Does this engine typically last for much longer than this? Also are there common problems that I can check before I buy? I'm on a bit of a budget, and the price is right, but if I need to spend another 10 grand to replace the engine, I'll just go back to looking at new domestics. Any advice would help. Thanks in advance.
