Depreciation

Our experts predict that the A5 will hold onto 33 to 50 per cent of its value come trade-in time after three years and 36,000 miles. Diesel-powered examples hold their value best, while the higher-powered petrol options in expensive Vorsprung trim are best avoided if residual values are a concern.
