Not a major component and won't effect handling? Then why an MOT failure? My car failed on this about 2 months ago at a long established and respected garage. The tester himself told me that it would not have failed a year ago as the legislation had since been changed.
I work in the motor...
Same on my CLK.
Annoying thing is that this a failure that will catch thousands out. This time last year this failure did not exist, it has been dreamed up to create work and parts sales for the motor industry. When was the last time you heard of an accident being caused by an anti-roll bar...
