Hi everybody. I'm set on buying an A4 but I'm unsure as to where to buy it from. I was in the audi dealers looking at their approved used cars but when I compared the prices of equivalent cars on autotrader there was a difference of £1000's between the two. There appears to be a lot of benefits to buying from the audi dealer but are these worth the additional cost? Any advice or comments would be appreciated. Thanks in advance!
