can anyone please provide a lead for sill protectors that actually fit a Citigo? I can only find products that fit the upper horizontal surface, I want to cover both upper and lower. I also need a decent bumper protector. I don't need anything elaborate, black plastic or thick vinyl would be fine.

I went to a local stripe/wrap stylist.

https://www.rearguards.co.uk - these guys are first rate and they used to do sill guards like you describe for the Citigo - can't find them on the website at the moment. best drop them a message and they might be able to sort you out as they hold templates on file and might be able to run some off for you.

I am also in Yorkshire, may I ask where this firm is and what they charged?, thanks
