As noted elsewhere, I've just bought a 2008 MINI Clubman Cooper S as a commuting car for MrsC. On returning from buying it in Plymouth, it drove fine, except for one issue:
When slowing from motorway speeds down to 50 or below, the steering wheel began to wobble. This would get worse and carry on until I either slowed right down to a virtual halt or accelerated again.
It didn't happen every time I slowed and it didn't ever become unmanageable, but it will need to be sorted.
My observations are:
The car is fitted with run-flat tyres at the front, but not at the rear. At first glance they don't appear unevenly worn
The car has non-standard alloys with spacers. I don't know whether the spacers are for practical purposes, to avoid snagging, or for cosmetic effect.
I don't know if spigot rings should be or are fitted.
I really, really hope it's not a symptom of a shagged steering motor.
Any thoughts, O Gurus?

Silly question, but Have you checked the wheel nuts are tight?
The only time I've experienced shudder (rather than wobble) is warped brake discs. They tend to only manifest when slowing down from motorway speeds.

Also, try and find out the stock offset for standard wheels and compare with the effective offset of the current wheels and spacers. Changing the offset changes the scrub radius that can then have quite undesirable effects. I'm very much in the school of leaving the suspension of road cars as it was meant to be and the scrub radius seems to be an especially sensitive parameter carefully selected by the original engineers and testers.
