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.

With two monster V8 engines in the line-up, it would be optimistic to imagine running an AMG GT 4-Door Coupe on a shoestring. But while it has a massive thirst and is hardly a front-runner in the race to save the planet, the truth is the big AMG does pretty well by the standards of its class.

Driven like an ordinary saloon car without dipping into the extraordinary reserves of power should allow drivers to average MPG in the low 20s, but of course any lack of discipline will result in a hammering at the pumps. You wouldn’t have to drive an AMG GT very hard to breach the MPG ‘teens’, and single figure fuel consumption is a definite possibility if you drive with a degree of commitment.

Emissions levels range from 252 to 257g/km of CO2 for the V8s, which means drivers will be faced with the highest possible company car Benefit-in-Kind tax rate of 37 per cent. Road tax will also be steep with a £2,070 first year charge and a £310 surcharge for four years after that. The GT 53 six-cylinder model fares a bit better with a combined mpg figure quoted at 31mpg and C02 emissions of 215g/km.

Servicing and consumable parts replacement won’t be cheap either.

Insurance

You’re going to have to fork-out significant insurance premiums to run an AMG GT of any kind, as a Group 50 insurance rating applies. That’s a fact of life for any car with similar performance of course, but it doesn’t sweeten the pill.

Depreciation

While the two-door Mercedes-AMG GT Coupe has held onto its money well, expensive AMG saloons have traditionally shed value at an alarming rate once driven out of the showroom. We don’t expect miracles with the GT 4-door, but its more bespoke nature may make it a slightly safer bet for your money than say an AMG E 63.
