Hi Keith,

The reason the A4 is probably the same price as the A6 is that it’s a higher-spec S line car, whereas the A6 is an SE. No reason to avoid the bigger saloon, of course, but we’d recommend the A4 because the A6 will be a C7-generation model, which was superseded by the C8 A6 in 2018, so the 161-plate car you’re looking at is based on much older Audi technology than the A4 – which, in turn, should be an early example of the current ‘B9’ generation vehicle. It’s therefore less likely to depreciate as heavily as the A6 from this point forwards.
