Audi unavailable is it that there is no market for them in the US, every major BMW performance shop carries BMW performance parts directly developed and produced by BMW Motorsport. The parts don't have a cheap price but have the guarantee to the purchaser that they are 100% bolt on trouble free performance parts which have been extensively tested inhouse to satisfy our cars need for performance. Also these parts would be dealer friendly toward our warranty to some point. I guess the other car manufacturers are leaving Audi in the dust because they are giving their customers what they demand, while Audi is silent and just waiting for the opportunity to void your warranty for the simplest mod on your car.

I think MTM but only in Europe

BMW M and TRD are in house. MTM has ties with Audi, but it's not internal.

Bollinger

Hartage, AC Schnitzer and Dinan. There's at leaste one more too and I can't remember the name.

BSM

Responsable for building RS4 and other specialty models. Collaborations with Cossworth, Porsche (in the past) etc.

MTM used to have close ties to Audi, and I believe ABT also has close assoication, but neither are considered factory tuners as far as I know.

Unfortuatly all the cool stuff, upgrades, options, and vehicles Quattro builds are for the most part NOT sold in the US.

I would be really nice if AOA could agree to import the Quattro goodies, or if they could make a Eurpean delivery system. Yeah, they would have to meet emissions and safety standards (which I don't think Audi would have a great deal trouble doing do.)

Nissan does the same, though. Nismo makes some sick upgrades and automobiles that will never make it to the US, for the same reasons Audi won't sell us their RS4.

Nearly every brand has tuners- what's your point?
