According to Sky epg, S1 ep2 is on next Wednesday at 8pm.
That is what last nights episode was listed as, however, the details of the items on the show don't match up, so who knows?
Just to confuse further, next Thursdays show is supposedly S1 ep1.
Just looked on Wiki at an episode guide, and last nights show is ser25 ep3, according to them.
Actual items on last night were Citroen Cactus test, Jag v Merc, Tiffs first racing car v a modern Lotus.
