The execution

The works Group B car: ~950 kg, up to 473 bhp in evolution trim, and the 1985 RAC debut win. Group B died before it could finish the argument.

RM Sotheby’s twice states 28 Corsa were constructed and the public registry lists 28 competition chassis; a separate registry field says 26 without explaining the gap. Works cars ran the Martini colours in period; ex-works examples trade on history rather than condition, in a different register from the road cars.

On the record

- Debut win: 1985 RAC Rally
- 28 competition chassis on the public record
- Ex-works car: £1.64M, RM Sotheby’s London 2022
