he's quite easy to spot is the lesser spotted stromba, his head is the same size as the average microwave.
Plus you would have heard him shouting out the window how you don't need those dampers
I've probably never met a techy at a dealership that actually knows what he's on about. Servicing and parts is all I use them for, advice i'd go elsewhere
its what stromba does, if he went on blue peter he could turn half a lemonade bottle, some sticky back plastic and a blue pen into a williams if he wanted.
