Local independent dealers of car parts can be good priced some times. Theres a place Knighty introduced me to called npa Ltd and they do all sorts. Basically they sell things like Bosal back boxes for my car, where its not exact pug, but it still does the same job and like half the price.
Literally, £60+ at pug for a back box for my car, about £30 for the part at NPA.
But of course you need to know what you want
