Couple of questions :)?

My car is a Renault Clio Extreme 16v 1.2 2005/55 reg

I have a cigarette burn on my back seat right in the seam. Can i get this fixed or will i have to fork out for a whole new bottom seat?

Also somebody stole my side trims (i think thats what you call them (they run down the side of the car)) where can i get these cheap?

I'm a girl and need help with this sort of stuff :)

Thanks

Georgie
