You will soon not be able to drive it into city centres and if you live in London, I would imagine the Congestion Charge will cost you. Get a 1.0 litre Turbo model - mine will do 117 mph (apparently) and I've managed to get 46.4 mpg over 36k miles of owning the car.
More serioysly, other than avoiding the auto gearbox, there seem to be no other major issues with the B Max and the diesel engine is very good compared to most oil burners
Thanks for that @cianpars! I'm actually in Ireland so no congestion charges here yet. Good to hear there seem to be no other major issues. It's a not a very common model here so wanted to get some feedback! Thanks.
