Should I buy a 2008 335i with 30k miles on it?

What is your question?

I am considering purchasing a 335i that has 30,000 miles on it. This would be a daily driver. My concern is about reliability issues and maintenance costs. I currently have an Audi A3 that I purchased new 10 years ago so I am somewhat used to the idea that German cars can cost a bit more to maintain. How does BMW reliability and maintenance costs stack up to Audi? Clean carfax, and 1 owner car. Any opinions would be appreciated. Thanks
