Costs & verdict
Everyday costs, plus how reliable and safe it is
The Audi S7 considerably undercuts the Mercedes-AMG CLS 53 as a cash buy. Expect similar resale values to the CLS 53, too, which should also bestow it with competitive PCP repayments. The S7 really shows the CLS 53 up when it comes to fuel consumption, too — being a diesel you can expect it to return several MPG more than its petrol rivals. Company car users will still find it in the top bracket for benefit-in-kind (BIK) tax., though.
The standard S7 comes very well equipped, with 20in alloy wheels, privacy glass, keyless start, leather seats (heated in the front), and all those infotainment and visibility aids we’ve mentioned previously.
