Possible swap

I have a 2009 A4 3.2 petrol saloon that has some body work dinks and dents 

I have lost the service book but I have some receipts for previous services and have just had service done , oil , plugs etc

It keeps throwing up gear box malfunction but you can continue to drive , the wiring has been checked but no fault found and the car behaves like normal 

I'm looking to do a swap or sell , open to either  

Its full leather , electric windows , no sun roof , fully working a/c , twin front zone , aux plug point , it's not the full bells and whistles model 

Reason I need to try and off load it is because my wife uses it daily and it's costing her a lot of money these days to run it 

I've been as honest as possible , this may or may not work but just thought I'd give it a try on an Audi forum 

Cheers
