I just 'live with' the space-saver on mine.
While I too, dislike the idea of a space-saver, it is still better than not having a spare wheel at all - as some new cars have; or worse still, a next-to-useless repair/inflate emergency kit.
The space-saver is just to get me to the next tyre-fitting shop if I have a major drama damaging a tyre so badly it can't be used.
In other words, it would only be on the car for a few miles and not many minutes.
I think I can live with that when put into that context.
