Thanks for all the compliments everyone.
Novass: I'm hoping to meet someone that upgraded their own RS6 exhaust and just has it lying around and wouldn't mind getting rid of it cheap, or free. =)
Dani: From what I know, the RS6 Avant looks exactly the same as my S6. Both share the same fender flares, which are much wider than the standard A6 and both have those skirt things towards the bottom by the rockers. It's just the "motivation" that is different.
T-Bird: The MDX is my wife's car. I hate SUVs and initially, was trying to get her to buy an S6 Avant or 540i Touring, but she wouldn't bite and wanted something bigger. The S6 is my daily driver, and at times, when I would have to bring my son out, moving him in and out of the back seat was difficult...so this was my opportunity to move up a little. =) Incidentally, I recently moved a bunch of stuff, and but for the fact that the MDX's cabin is slightly higher, with the seats folded down, my S6 carries nearly as much as her MDX. And, I've got 100 more horsepower and waaaay better handling. Plus, Acura's AWD can't touch Quattro!
Sameerrao: The RSA is doing well. I didn't have a chance to drive it for several weeks and took it out last week to run errands. I recently upgraded the exhaust manifolds, and haven't finished the project yet, so it's go not heat. Brrrr...cold! But, it feels much faster than with the OEM manifolds. I love that car!
The weekend after I got the car, I went to the Bay Area to visit my family and to show my friend the car (he has an S4 biturbo Avant). I smoked an E36 M3 on the freeway. =)
I saw the newer V8 S4 Avant on the highway recently, great looking car. I wouldn't mind one, but for the smaller chassis. Very good lines, and aggressive, but subtle bodywork...
