Terrible photos ahoy but hopefully gives you the idea (afraid mine are the 17" monzas):


They're a bit marmite in the reaction I get - most people like them and have actually come up to me to comment on how well they set off the alloys (they go with the red calipers / grill trim / red & silver nurburging badge on rear), but one friend is not keen. Everyone can't deny they do the job though - was forced against a kerb on a narrow village road by an impatient truck within a week of ownership. Alloygator took the brunt of the damage. Not been able to perfectly restore with a stanley as they claim is possible, but still far better than £50 on refurbing the alloy...
