Welcome to the forum.

Might want to post in the subforum for the actual vehicle in question.

Will do thank you

Put it through an mot and come back with it's fails and post in relevent section...welcome...

I take it you are now driving a vehicle that doesn't have a current MOT, in which case a roly-poly drive could be the least of your worries.

Lift and monster truck tyres turns it into a bad driver. Shock. Horror. Actual fainting.
