I have 3 BMW's I like, the X3, 325I E90, and the Z4. I'm just wondering which one is the best, most reliable, and has more for its money. Tell how much a year for maintenance on any BMW you've had before, or these above if you know them. And what does that include. It will be my first car, but I get around 380 a month in a month where I don't mow the lawn, and when I mow the lawn I get like 520. If I get a job it will be like that (hopefully I can get the job I want, wish me luck!) anyways these are my only 3 choices, and please tell me their price in about a year. I plan on buying a car next December of 2009, or in January 2010. Hoping the cars will be around 10-13 grand by then.
