Ok, I'm just dipping my to in the water here but don't want to get burnt, just saw a 12000 mile MP3 with the aim of purchasing, now I'll admit to knowing next to zero about the steering system but there was about 3mm play (a knock) between front wheels, by that I mean if you grab both wheels and pull them towards and away from each other, there is play. Now surely play means the tracking will be all over the shop and that maybe the cardan joints are sloppy. Just wondering if I'm being too fussy or if it's a valid concern.

Sounds like bad front wheel bearings, a relatively easy fix.

The Achilles heel of the MP3 is the front suspension.

Better check the steering for a notch. Best to check the service history and verify it got the inital 1K km/600mi initial service. This service includes lubing up the steering bearings, and every 10K km/6K mi.

If the steering bearings require replacement, bargain hard on the bike as it is not a cheap repair.

I have had 2-3 mm of play between the front wheels for about 30,000 miles now. The front right wheel bearing is a bit loose. I got the parts but never got around to installing them.

Best case it's the wheel bearings. They are quite small. You'd have to isolate the movement to be sure. Next possibility is the strut bearings. If the castle nut is loose or the bearings are worn the strut will wiggle. Or could be the steering tie rod. Same deal. Need to figure out where the movement is coming from.
