Bent my front NS alloy in a pothole yesterday so need to get a new wheel. Luckily the spare was an original alloy so I'm thinking I'll just get a space saver or a cheap steel wheel to put in the boot. Assuming this is not a stupid idea what should I be looking for? Would a space saver be useable or do I need to look for a steel wheel? Are wheels from any other models compatible eg Golfs? Thanks for any advice! (& yes, I will be claiming from the council - 8ft-wide road, giant potholes on both sides, would have had to drive through the hedge & into the field to avoid them both...)
