If it can be fitted after a puncture, it can go there permanently (it still has to fit and be safe so 1 day, 1 week or 10 years, the effect is the same, it either fits safely or it doesn't).
If they've replaced the full size with a space saver, it sounds like that's predominantly as a weight and cost saving measure.
Hi I am looking at a 2019 HSE Lux 7 seats I will fit a tow bar myself that's not the issue, just wondering if you can buy the spare wheel holder for either a space saver or full size, the car has twin exhaust at the rear.
Looking for a fixed flanged bar as I put bikes on the rear.
Any help greatly appreciated
