Have a look at GSF car parts on line. Enter easter43 and get 43% off. Don't know how long the offer lasts though.
Good site that is Ed. Put yr reg number in and after that everything you click on is specifically for your car. Have had work done on the tin top recently so not much I need atm I think.
Ordered a rear wiper blade from a company on ebay last week, they sent totally the wrong part. I find getting the right bits on ebay sometimes a minefield as I am sure they all drop ship and never actually see the parts themselves. If they had they would have seen clearly written on the box that the wiper blade was for a BMW 5 series Touring E39 - which is not my car! Got a refund though and they let me keep the wiper blade so it is going begging if anyone has that car. Rear blade for the hatch window. Bosch too! :)
