Ok bit of an update... and advice from any one whos been in this situation would be good.
To cut a long story short one of the rs4 alloys on my gti were cracked and the tyre loosing air. I went up to elite in essex to sort out a new one. I also took the one of the fuel alloys with me for the chap to look at. In line with what Wayne said, he also said that any wheel which fit a mk3 gti will fit a beetle.
He looked at the wheel and said it would be way above an et45. The mk3 gti both pcd100 would take bettween a et 35 and 42 give or take 1 -2mm. The way the fuel alloy fit it was more than a et42, more like an et 45 or above. In his opinion there was no way it would fit on a beetle, or any 5 stud pcd 100 vw on the front wheels without spacers.
I bought these wheels from a car dealer via ebay who has a shop. I paid via pay pal and used a mastercard. Has anybody had this sort of sitaution before. Should i persue him for a refund. He advertised them as being suitable for a golf/beetle etc..
What would mt best option be. Go for him or try and sell them on
