Moreover, the Plus is another £3,085 on top of the regular TT RS, making a convertible more than £50,000. However, it's forecast to do  marginally better than its competitors.

The probability is strengthened by the fact that few will be heading this way, Audi planning to sell just 400 RS coupés and roadsters a year.
