Starting at £31,955 for the 2.0 TDI Ultra in Sport trim, the TT Roadster is almost £4k more expensive than the entry-level BMW Z4. It also commands a £2k premium over BMW's four-seater 220d Sport convertible.

However, it remains a marginally cheaper purchase than the diesel powered Mercedes-Benz SLC 250 d and considerably less than Porsche's entry-level 718 Boxster.

Combined fuel economy for the TT Ultra TDI is a claimed 65.7mpg, while Audi quotes 42.8mpg for the TFSI blown four-pot petrol.

Audi only charge a fraction more for the front-wheel drive 2.0 TFSI petrol variant.

The Sport's standard suspension set-up accompanied by its 18in wheels are more suited to UK roads and make the no-cost option S line suspension, its 10mm lowered ride and 19in alloys unnecessary additions.

Running costs shouldn't be too steep, either. Combined fuel economy for the TT Ultra TDI is a claimed 65.7mpg, while Audi quotes 42.8mpg for the 2.0 TFSI blown four-pot petrol. The diesel variant also has low CO2 emissions at 114g/km, so could be a tempting option for company car buyers.

Audi TTs have generally been rock solid with residual values and our experts predict the Roadster will be no different. Put simply, it's got all the practical and financial boxes ticked.
