According to Sixth Sense today: Apparently the process for BFG registering cars has changed, allowing a full 45 day period to get the Car registered with BFG however, lighting test and if required BFG test must be done first. How does that leave those (i.e me) planning to acquire a new tax free vehicle just prior to posting back to the UK. The rules are that it has to be BFG'ed for 7 days. Previously this fell within the 30 days that you had to get a BFG lighting test done, hence you could get away without buying the lights . Surely I don't have to buy continental lights (£1500+) for 7 days use? dealers certainly aren't aware of this change. I was told that as I was returning to the UK it didn't matter that my model spec came with adaptive Bi xenons etc. Had i been staying in Germany I would have been warned off buying this variant because of the massive extra costs. man I #@#*ing hate BFG motoring regs !!
