my drivers side front seat belt has started cutting into the plastic on the pillar, just passed mot but they said it won't next year and quoted me £570 to replace

what do you think

Its an MOT failure.....If you asked a Skoda dealer, then that price makes sense. Try with a local VAG specialist and see if you get a better price (would be expecting £300-350 for that type of replacement)

Just source something 2nd hand on ebay as plenty of breakers out there

Or carefully de-fluff the edge with scissors and a lighter.

I had this on my Scout when I bought it (was an advisory) £50 for a reel from a breakers and less than an hour to fit. Who ever quoted 570 is having your pants down. Longest bit of work was whipping the seat out to make access easy.
