Well I've enjoyed having my A3 but it was time to change.
If there was one bit of advice I would say is never try and sell your Audi on an Audi Forum. There are some great people on here but there will always be the odd few who are obviously second hand car salesmen at the weekend or at least in their virtual reality world.
Hold off and you will get what you want for the car
How did you sell it in the end? Did you try eBay?
2004 A3 Sportback 2.0TDI SE, RNS-E Sat Nav SW0650 TMC, 17" Star Alloys, Xenons, DIS, Rear Mats & Sunblind, Alu trim, Ebony Black pearlescent
2006 Honda Accord EX i-CTDI, Arctic Blue, Leather, Sat Nav, XCarLink
never actually thought about ebay, in the end sold it locally.
