Honestly, while automotive culture might have deep roots in UK, it appears to not apply to London itself. 4 days in and it is clear London is not car friendly, particularly for those who want to mod their cars, which is understandable considering how the city is. It's like being in NY or Paris, if you live here, a car is just impractical so not so many people care about them. 3rd day in, this was the first "modded" car I saw, a stark contrast to my SoCal roots. Still, at least it was a clean example. Can't go wrong with a Mk I!
