The BMW M2 Competition, Porsche Cayman and Porsche Boxster are all around the same price as the TT RS, but you can pick up an Alpine A110 for less. However, don't forget that the Porsches will require you to fork out more on optional equipment to match the TT RS's standard features, such as climate control, heated seats, cruise control and leather seat trim.
The Porsches are predicted to hold onto their value better after three years, though, as is the A110. The M2 Competition, on the other hand, isn't. Don't expect the TT RS or any of its rivals to be cheap to run, though, with fuel, tax, servicing and insurance all costing a pretty penny. And with its fairly high list price and CO2 emissions pushing past the 180g/km mark, you won't find it a cheap company car, either.
Standard safety equipment includes lane-keeping assistance, with blindspot monitoring and traffic sign recognition optional. Sadly, though, automatic emergency braking isn't available at all. That's part of the reason why the TT RS gets only a four-star safety rating from Euro NCAP, although to be fair, its key rivals haven't been tested at all.
