I have got the Vectra GSi back end twitch. The car has been doing it ever since I got it back at the end of October 2006 but tyre wear has recently become a major issue.

I think it is the often-reported wear and tear in the rear suspension top link bushes and am having the back end checked tomorrow by a local, friendly (i.e. non-VX ) garage. If there is a problem, then I'll be phoning my local VX stealer because the car is still under Network Q warranty.

If the back end is adjustable, as I think it is, then I'll be looking for a decent laser four-wheel alignment centre in the Welwyn Garden City/ St. Albans area.

Ta muchly.
