Even the cheapest GT Roadster costs more than £100,000, and fuel, tax, insurance and tyre bills are also going to be steep. But, then, the same is true of rivals, and if you can afford to buy it, you can probably afford to run it.
Just bear in mind that servicing has to be carried out every 15,500 miles, whereas the interval for most 911 variants is 20,000.
The GT Roadster comes pretty well equipped, with dual-zone climate control, keyless go, automatic emergency braking and LED headlights all standard, although there are also plenty of pricey options: everything from track-focused ceramic brakes to carbon-fibre exterior detailing.
In addition, Mercedes lets you choose from 11 standard paint colours and three roof colours (red, black and beige).
