Random snippet from yozzasport for reference on other cup specifics for reference:
The total sold for the UK Market were:
2392
The 172 Cup was billed as the lightweight track orientated weapon. It had no ABS, no Xenon Lights, it had a cloth interior, loosing the heavy leather, no aircon, lightweight glass (front windscreen had no IR sheet), it had a slightly wider track down to the Speedline Turini wheels, and again a slightly different gearbox – the JC5-129. It had no spare wheel, but instead some rapid inflate puncture repair fluid. Sound deadening was removed all over the place and a nice lightweight weapon was produced. The 172 Cup was only available in Blue for the most part, but late on, some silver examples were released – some with Climate Control.
