2009 Audi A5 3.2 engine... reliable? Should I sell?
 

I live in LA. Have about 43,000 miles on it. Reason why it's so low is because I use Metro a lot. Also, I've had really good commute karma over the years.

I've kept up with maintenance. I stopped going to the dealers after Audi Care ran out, but have been going to a very reputable independent garage that specializes in German cars.

Recently, I had brakes replaced, again, and I'm trying to address an oil leak. Basically, I THINK the car is in good shape, but a part of me wants to sell it before this car starts getting "expensive." How reliable are these engines? Am I being paranoid? I'm just worried about soon having to spend a grand here, 2 grand there, 600 here, etc.

Thoughts? I do realize that since this car is paid off, it's not like I'm saving money by leasing a new, more dependable model with a more comprehensive warranty. I'm kind of rolling the dice. I'm looking to get a PHEV.
