Cliff, make sure you start another fresh topic under Sturgess for any feedback so others in the future will be able to find it easily.

Had mine back today - and as luck would have it the dealership could not do the 4 wheel alignment themselves so they farmed it out to a place in Nottingham called Nottingham Car 4 wheel Alignment Service. (Unit 7, Little Tennis St, Nottingham, Nottinghamshire NG2 4EL
Tel: 0115 959 9144 )

Apparently they do a much better job AND it only costs £48, as opposed to the £240 Stratstones were trying to get me to pay!

Apparently mine was out by 4 degrees at the back and 2 degrees at the front...no wonder it was drifting left, it was all trying to go in different directions!

Thanks to RRUK for the alignment heads up.(above)
These guys really know their stuff and only do tracking and balancing, well worth recomending.
