Hi Shaw8670. My previous Mk 3 with 18inch wheels and had no spare and i made the mistake of buying the "correct" space saver from Skoda dealer. I do a lot of miles and didn't want to rely on a repair kit. Cost the thick end of £200 as i remember. Fitted in the recess perfectly with the polystyrene insert taking up the gap between the wheel and boot mat. When i changed the car for another Mk3 which had a full size spare i kept the space saver thinking i would sell it on easily as it had never been used, genuine Skoda, tools included part etc. As it turns out not a lot of people want them, not locally anyway. I think the steel rim with suitable tyre is the most popular option and perhaps only consider a space saver for ease, from a selection POV. I still have my space saver in the shed getting in the way. I'll get round to advertising it again at some point. I cut up the poly insert and used part of it as a storage box above the boot floor. When the spare is in the recess there is really very little room for anything else.
