Hi, for a fast car that is not Japanese, hummm let me think. Well European cars are expensive to maintain overall. I had a few myself, used to have a 325 convertible, and M3 cabrio, then moved to a Porsche. My experience European cars are well build and it will last you a long time. Especially the Porsches but the oil changes are 400 plus. I would certainly recommend BMWs, 325 or 328, for more affordability. If you are located in Toronto area, you can browse through my friend's dealership at http://www.whitbymotors.com
they do carry some imports such as Nissan Maximas, Lexus, VW, and Audis.
