Sorry gml, I forgot your boss doesn't have to justify his job or how the money is spent, doesn't sound like he is hard up for a quid and your vehicle problems probably don't go across his desk.
Yesterday I pulled my air conditioner out of the wall because the fan had begun hitting something. 2 of the rubber mounts had started to fail, quick repair with a couple of Victa height adjuster springs and it is back in service. This air con unit is one that was built to last, I bought it in 1975 and it is still going strong
