Audi S4 Cabriolet.
What to Check Before Buying.

The Audi S4 Cabriolet combines quattro all-wheel drive performance with open-top driving, built between 2002 and 2009. These cars appeal to buyers wanting year-round usability with a 340bhp V8, though running costs are high and age-related issues are increasingly common. Most examples have covered significant mileage by now, making thorough pre-purchase checks essential. Expect to find well-maintained enthusiast cars alongside tired examples with deferred maintenance.

The average used car has 3+ known model faults the seller won't mention.
