After replying to a Skoda customer satisfaction phone call I have been sent a £30 voucher to use against the purchase of accessories. 

Has anyone any suggestions of citigo accessories around that price area that are available from Skoda dealers?

Maybe car mats if you haven't any? Rubber boot mat or mud flaps? Maybe cleaning products or things like screen wash or oil for topping up? You can buy packs with warning triangle,high visibility vests and first aid kit. Bulb kit or spare wipers for when they need changing? Fire extinguisher,keyrings,Skoda cuddly toys,diecast model of a Citigo?

Maybe have a trip down to the dealer as they usually have accessories on display and the parts manager will hopefully be happy to advise.

A variable boot floor is useful but it'll still set you back abit with that coupon, probably around £80 with the coupon.

As Jonny says I personally would put it towards the variable boot floor modification..... Usual price is around the £120 mark from most dealers so would be a roughly 25% discount and you could get around £60-80 when you take it out and sell it when you get rid of the car.... So in effect a free upgrade for you.
