He's very courteous. He makes everything simple. I'm not very mechanically inclined, so he explains. He gives you an idea what's going to break, but he does not pressure you. The advance repairs he sees he says you should get this seen. He's kind, when you speak to him its a friendly environment. He's very kind very understanding when you speak to him.

Finding parts is very easy and these are pretty good cars if the previous owner maintained a good history of services on the vehicle.

Sounds like you have done a lot of work to the car. If it's running well, no check engine lights or problems felt at this time then it may be worth to keep. You can always bring it to a shop as ours and we can give it a look over for you to identify any potential problems which may be coming up. If you desire a change and want something different then maybe it's time to sell.

As your engine gets older it is normal for it to consume some oil, it is also possible that you may have oil leaks. Average vehicle can consume about 1/2 to 1 quart of oil between oil changes. If you hear noise from the engine such as a knocking or loud ticking noise there may be more going on with the engine that requires attention.

Over filling the oil could cause a leak to develop from the valve covers which will spill into the spark plug tube. I would more then likely think that it's from your valve cover gasket, but it should be checked out. BMW is notorious for oil leaks.

Your vehicle may have developed a leak in the ac system or it could be electrical such as a relay or fuse. We could check it out for you and let you know.
