I just called them up and its £30 a wheel including tyre removal, re-fit and re-balance, turnaround time 2-3 days. However, there is nowhere to store the car whilst they are being done so he suggested doing them one at a time, swapping the space saver around as each wheel is in the shop. This sounds like a total ball ache, surely this isn't the standard practice? Also he said "my man" literally every 5-6 words!
