I'm looking into buy a 2009 A4 Cab and was wondering if anyone could let me know of any issues I should be aware of before purchasing? I don't have a garage and haven't owned a convertible before. Any advice is helpful.

Also below is the VIN number, please take a look at the vehicle and tell me what you think. Is it worth 20k? Thank you very much in advance.

VIN: WAUDF48H69K004716
