Representative Example - Personal Contract Purchase: Cash Price £10,000.00, Deposit £1500.00, borrowing £8,500.00 over 4 years at 7.4% Representative APR (fixed). 47 monthly payments of £132.04 followed by a final payment of £4127.50. Total cost of credit £1833.38. Total amount payable £11,833.38. Based on 8,000 miles per annum. Excess mileage charges apply if exceeded. Finance subject to status 18+ only.

Running the Mercedes-AMG 4.0-litre V8 petrol engine should point to a level of tried and trusted reliability for the DBX, while Aston itself has developed the car from the ground up and will be demanding nothing less than a dependable, volume-selling product.

The DBX probably won’t be tested by industry safety experts, Euro NCAP, due to the relatively low number of sales compared to other mainstream models. However, in addition to the raft of front, side and curtain airbags, there are also additional active safety features as standard, including adaptive cruise control, lane keep assist and auto emergency braking with pedestrian detection. The list of safety tech continues with systems such as traffic sign recognition, a lane departure warning, a rear cross traffic warning and blind spot detection.

Warranty

Aston Martin provides owners with a three-year, unlimited-mileage warranty, along with the option of extending the cover for 12 or 24 months when it expires.

Servicing

Scheduled servicing costs are fixed, with Aston suggesting V8-powered vehicles are seen by approved technicians annually or every 10,000 miles.
