Robert, thanks for the offer, but your V710s will put me in FS. I'm running in SK1. ;)
George, yes it's a slow leak. It started this morning on my way to work. The low warning came on once, then I pulled over, found a gas station to fill it up with air. Then drove about 10 miles, the warning came on again. When I got to work, I checked the tire but didn't see any nail or tear or crack on the tire. I'll go to a tire place during lunch, and hopefully it can be fixed. I don't want to run in SK1 with a SS index.
Greg, that's a tough question. I like the S4 a lot, but I also like the 335i a lot too.

What is your brother looking for in the S4? Performance? Speed? Comfort? Or something else? Maybe we can talk more this Sunday. I actually took both cars to AutoClub Speedway last year for my own comparison, and I wrote something about it, here's the link:
