I was stopped one day at a party by a woman who said, "Are you the guy who has the A5 that was parked outside of the cleaners?" The exterior styling is amazing. It's a true head-turner. Nothing like it. I have the windows tinted and the rear badging removed (except the Audi circles) for a stealth look. It's a bit over-priced though. For nearly fifty grand, you get cheap floor mats, only 260 HP, no push button start (that package is another $2,000) no auto folding mirrors, cheap "leather" and an engine that burns about a quart of oil every five thousand miles. Notwithstanding, Audi hasn't imported a lot of these so it won't be like the A4 where you see one on every corner. A blast to drive.
Lexus type quality and reliability. in addition, floor mats befitting a car at this price point; more horses / better fuel economy; genuine or better leather with more support; auto folding mirrors; push button start that is standard; traffic updates via the nav system (not available for 09).
