335i F30 M Sport vs 2012 S4 (considering tuning capabilities)
I get it that there are a lot of threads comparing the two cars stock vs stock. Long and short of it is that BMW has the better fit and finish yet the Audi has the better straight line (and debatingly handling) performance.
My goal is to buy one of these two cars and put a light stage 1 or 2 tune on it without going too wild with bolt ons. I want something very fast but with a stock look (I love the performance of a friends 2007 with a stage 2 jb4 tune). I really like the look of the M Sport over the Audi and an trying to justify going that route. In all reality I wish it had the N54 engine since I don't think tuners will ever get as much HP out of the N55. Can anyone give me good reason to not jump ship to the Audi?
