You will have fun driving that around the streets of Gib 
30% import duty on customs valuation.  Then you have to pay for MOT £40-45. Â
Or you can pick up a car pretty cheap as people leave all the time and although they advertise them for high values when it comes down to parting with the cash you can get a good deal.  Plus it will fit into a car parking space
The other thing to consider is - you don't need a car if you can walk - its helped me out no end, lost pounds.
