The Cog respray an Aston Martin Lagonda a shocking pink for Europe's biggest car collector. Richard's daughter Izzy discovers a passion for racing. Richard gets carried away and enters them into a race, prompting a last-minute bout of parental nerves.

With the workshop haemorrhaging money, Richard brings in heavyweight help. Attempts to make money through selling merchandise backfires.

A 1950's American pick-up truck offers the Cogs their first chance of car-show glory, if they can restore it to pristine condition. And Richard gets a shot of driving in the biggest classic car race of the season, providing he can impress his mentor.

Much excitement as the Cogs head to the Isle of Man TT to launch a new British bike brand. A racing Mini needs brutal surgery after a crash. And Hadrian calls time on Cog Racing so Richard enlists old friends Les and Zog as his stand-in race team.

New staff find themselves in at the deep end restoring a unique 1960's concept car and a rare Lotus. Richard follows his dream of big-time racing and attempts to get his hundred-year-old steam car back on the road threaten to run out of puff.

The Cogs take centre stage with an eclectic display, including the last ever Lotus Europa, at Britain's premier car show - Salon Privé. But glory is short-lived. When Richard returns James May's restored Triumph Stag it doesn't exactly go as planned.
