A cheaper option if not ordered as a factory option may be tolook for one from an insurance write off VW Tiguan as the wheel fitment is possiably the same. I purchased some Audi alloy wheels for winter tyres pre delivery of my Q3 but ended up putting them on my VWTiguan with no problems due to late delivery of my Q3.
Don't you just want to kick yourself for not going for the space saver option!!! It's not as if it was expensive! Considering I've been driving nearly 40 years and only had 2 punctures, I might be lucky!!
