I waited and waited for a black on black Q4 SV and eventually picked up a 56 plate a couple of weeks ago. I had to make a compromise on quality for spec, but the price was good.
Beware the following;-
Drivers wiper arm catching the bonnet. (Easy fix see one of my posts).
Front upper wishbone wear causing a clatter. (£114 part and a couple of hours to replace).
Non/partial functioning oil temp guage. (very expensive to fix, but is it worth it?).
Very uneven front tyre wear. (Maybe caused by wishbone).
Brakes pulling due to corroded front brake calipers. (Whole day with a wire brush and copper grease).
Drivers seat rocks slightly fore/aft due to worn bushes. (On my to do list).
Damage to engine undertray due to speed bumps. (On my to do list).
Bodywork pitting in front of rear wheel arch due to stones from front wheels. (fit mud flaps).
Other than that, great car.
