Tim and Fuzz take on their first ever rally car, a 1989 Peugeot 205 GTi that turns out to not be all that it purports to be. The car belongs to veterinary surgeon Jeremy a once keen amateur rally driver whose racing ambitions were curtailed when his wife developed brain cancer. Former Monte Carlo winner and race legend Paddy Hopkirk joins the team to give Jeremy a day to remember.

Tim and Fuzz hope to surprise bubble car owner Sam with a secret fix-up of his much-loved Messerschmitt. But the tiny car proves a big challenge for the boys.
