I bought a VT back in Jan drove it for 3 weeks and found massive cracks in both struts.
It is a common problem in the VT and VX's it was corrected after that. It went back to the car yard and they repaired it after alot of arguing....its just under 6 grand to fix cracked strut towers cause they have to level the car again and then bog it with whatever they use...EXPENSIVE DAMAGE HUH!
Its not structual its a cosmetic fault in the car. They are not welded as apparently it stops the airbags from going of. You can't claim it on insurance either as it classed as "wear and tear". Basically in a lowered vt a pot hole can do it..and if its a v8 the power can do it as well!
So if you repair (6 GRAND!) deffinately a strut brace to minimise the chance of doing it again but it can still happen....in other words they are a problem car!
