EH75

I need a replacement 18" Neptune alloy for my 2010 VRS. I contacted Skoda and they want £334 for a single wheel! Any ideas where I can obtain one cheaper? I did try and order one through the "Parks of Hamilton" website but they cancelled the order as apparently these are no longer available through them, despite being advertised on the website. Background on why I need one: Tyre losing air on one wheel constantly. I have had the tyre replaced 3 times over a period of several years and looked at by more than one garage and it is still doing it. The car was owned by my dad before me and he hit a pot hole very hard on this wheel some years ago which is what I think caused it. Think it is time to bite the bullet and change the wheel instead of pumping it up every couple of weeks.
