The Britpart question........ Britpart don't manufacture anything, they are a wholesaler. They buy in from suppliers, OEM, Genuine and Pattern parts and then put them in blue boxes. This is why the perceived quality of their parts is seemingly so variable, it all depends by who and where the part was made and the specifications it was manufactured to.
In my case I am quite happy to use Britpart but for anything remotely stressed or important I would always specify the "G" (genuine) suffix parts. For bits of trim and none critical parts I save some cash and buy their pattern parts. I am fortunate that my local independent who supplies parts from a number of sources including Land Rover and Britpart are pretty good with advice on the best supplier for any application. If he says Britppart are fine or stick with Land Rover I generally go with what he says.
