Hi Michael,

They’re two totally different cars, and not really directly comparable. The A4 (and we really like the new one - it’s very slick and pretty decent to drive) is a competitor for the BMW 3 Series, not the 5 Series. The 5 is significantly larger, more luxurious and more expensive — and a terrific car too, but as we say quite different to an A4. Your 2015 car, depending on its condition and history, is probably worth around €20-22,000.
