Thought I would be polite and say hello having just joined, and to give you all a chance to shoot me down /ubbthreads/images/graemlins/grin.gif as I don't drive an Audi, no I have a Mondeo. Why have I joined this forum you may ask. Well I do like my car BUT I have heard that there are cars out there with better build quality. Having heard good things about Audi, and liking the look of the A4 in particular, I am eager to learn more about this marque. Could someone be kind enough to point me in the right direction to find out the difference between the suffix on Audis, S4, A4 etc and where all this fits in with the range. And have Audi made a diesel 4wd in the last 10 years or so?
