Not a bad episode, but I'm on average I'm not finding the current batch as interesting as the previous series (not sure this is a new series though - it's just more of Series 23). Anyway, if this episode had been mixed in amongst those of the last 'series', I'd have probably marked it down lower than the 8 I begrudgingly gave it here, but I guess it did have some fairly good bits.
The Euro-Nascar IMHO was more exciting to watch than regular Nascar, although like VBH's giggly breathless commentaries, Tiff can be much at times too. Jonny's piece, mixing the EV car review with exotic car spotting around London, was interesting having tried a bit of it myself - mainly from the top deck of a London bus, but I did score a Koenigsegg even though it was out-of-season! I'm not sure he actually told us how many million pounds he did see in a single day - I suspect he did rather well considering seeing just one Bugatti got him 3/4 of the way there.
