I wouldn't fit one never been a big fan of them. They looked good on the dimma clio's but they were a long time ago. Is this advertised as new seat leon cap or is it for the new seat leon..?
 
You might as well put in the extra effort and have a real race spec fuel filler.

Dimma caps are very 90's.

309 dimma, nice!!!!! (showing my age now)

306 dimma (maxi) the best ever but cost £,000's!!!!!!!
 
looks like a stick on jobbie to me!

and i would hazzard a guess that both the new and old leon have the same/similar caps?! :shrug:
