I know how much you all like a parking thread at the end of a busy week 
Bit of background, neighbours have got the builders in, and they've been a tad cheeky about parking on my driveway. I own the bit of drive that my neighbours and I use to access each of our houses, and they own the bit that's directly in front of their house (where the van's parked). On Monday the builders knocked and asked if they could block the drive for a couple of hours for a delivery, and I said yes OK. They then left their van parked over the access for the rest of the day. Was very tempted to go and have a quiet word but resisted the temptation 
Caved in yesterday when they were yet again parked on my drive (but not actually blocking me in) and said I was OK for them to park one van on my drive, but no more than one. They did the usual foot shuffling and "didn't know it was your drive" bit, and I thought that it would all be fine.
So today I go outside and see this!! (just to explain, finger in front of the car was to obscure the number plate but didn't notice the builder's plate was still visible 
)
AIBU to go and ask them to move? There's enough space for the Bmer to park on neighbours bit, they only need to pull forward a bit?? So parking where they have is just a bit of CheekyF**kery isn't it??
Only thing is, am not sure if car is Mr Neighbour's brother... but Mr Neighbour moves his car to the road every day so possibly not?
