...mk3?

my little bro is a proffessional snowboarder and left his mk3 in my garage which i now need to shift into another garage. 2 of his alloys(those ferrari type ones) have cracks in the alloy somewhere as its defintitley not the tyre.. i'm constantly having to fill the tyres up with air everytime i need to move it- pain the asshole. was thinking of puting some cheap rims on it while its off the road so i can move it - sell it

.
going to get in touch with vw breakers etc but how much we talking here?
probably just need 2 ....
anyone know how much a set of gl or diesel L standard rims be?
cheers
