So... a really annoying story.
I bought some new alloys from a garage up the road. Left my 18" Pentas with them and drove off with my sparkly new ones...Forgot about the Pentas for about 6 months...Phoned the garage, they still had them no problems.
Went to pick them up 3 weeks later...In that time management had changed. The new manager had thrown everything away!! Apparently I wasn't the only one who had left wheels there..
So although they were a bit scuffed I they were still worth a few quid..The new management advised me to review the back of the receipt..10 days to take your old wheels away ! Its a fair cop, I know its my own fault.
Haven't had the balls to tell the missus yet..
