I think central London is actually a pretty great place to drive if you can afford it.

Westminster council doesn't tow, so you never have to look for a parking spot.

Unlike some other European cities, the odds of being harassed by police while driving are essentially non-existent. Your car can be registered in Serbia and you won't be constantly pulled over and harassed like you would be in Germany, Netherlands, France or Spain.

I even spent a month driving around without any registration plates and nobody said anything (they had been stolen, I had to physically go collect new ones from another country).
