at around 30mph, doesnt do it on acceleration & it still does it if i coast in neutral.

It's not bad, but slightly noticable, feel like the effect of having slightly knobbly tyres on, but these
are Michelin road tryes.

Check the handbrake is releasing properly Nige, sometimes if it's
sticking a little bit you'll notice these symptons.

It's a big fecker of a car on 255 tyres so resistance might not be the way!!

First thing to note Nige is that P38 owners under no conditions do work
on their own vehicles ;-) (though I reckon by the end of this year P38s
with problems will change hands for less than a grand and then things
will change)

Take it to a garage who have an appropriate ramp to get all wheels in
the air at the same time and they can check it there, if it's not the
handbrake they can have a prod about while they're under there and see
if they can find what's happening. Is it happening all the time? If
so that should make it easier to find.

Aye, all the time, not too bad, but could be a sign of something going
south!

All i did was get wheels all balanced & swap fronts to back & it's fine!!

I don't know if these vehicles are unusually sensitive to tyres or what, but
I had BFG ATs on mine, and needed to have them rebalanced every 15K or so,
as a persistent slight wobble would start to set in around that mileage,
usually on deceleration first. Rebalancing cured it for another 15K. Never
had to do that on any other vehicle with those tyres, so maybe it's just a
"feature".
