There are companies and a lot of tyre garages who would probably be able to get these off. Iknow someone in work who bought a Rover, loast the locking wheel nut key and took it to a tyre garage and they took it off for nothing. She said she played the dumb girl game.(You say that to a girl and it's sexist, fine when they want it though)
To get 2 replies so quickly is great. I did try quick-fit and they were not able to help. However, I shall now try an actual tyre garage (fingers crossed).
Amazing - I really think this stuff should be recorded centrally and am really narked that peugeot just were not keen on helping.
if you or someone you know is in the AA they have a special tool for taking off locking nuts, should be able to sort you out
if no luck with then goto www.350z-uk.com and search for locking nuts or similar, also search for username chesterfield as he got the nuts removed for only £20 but can't remember where from
