its worth doing in you can find trust in the transaction , you will basically save the 30% loading a dealer puts on ( thats at least 30 , can be upto 60 ) , you will also have to deal with the paperwork and set the car up for an mot ( easy enough , fog light fitting etc etc ) , once its all done its worth while knowing you did it yourself , only downside is with a bit of looking and a haggle you should be able to find 1 in the uk already and cheaper
