Overpaid Train Driver

Good evening guys, just joined the forums. As you can see from the title, I'm the proud owner of a pair of Audi's finest. A 2004 S4 convertible and a 2001 S6, both have had long spells out of use and I'm slowly bringing them back to rude health. Look forward to picking your brains (which will probably be quite often) and chipping in my odd 2p worth. John
