Ah yeah. That's Uncle Benson selling for my Cousin George from Uganda.
Totally legit. You make a half payment. Then he ah.... well he try to send the car for delivery in person. If you pay the release fee up front they send the car on the first boat from Uganda.
Guaranteed to arrive in 10 days, or no money back.
Just put the number plate into webuyanycar.com and it comes up as a blue 2.5si Z4 first registered on 1/9/07. So in that respect it looks genuine but very odd that a tax check on the DVLA website can't trace the vehicle.
Someone is either about to get the bargain of the year or be ripped off.
