I'm not being unreasonable, I'd like to explain to my husband why he is being unreasonable 
He's complaining that a bloke down the street has a Mercedes. The bloke has been very ill and struggles to walk. We understand that he has financial help to have a vehicle, he's probably registered disabled.
DH has complained that this is "our money" (taxpayers) and why should we be paying for him to have "some fancy car."
I think that this is probably through Motability which is a charity? And therefore they will have probably struck up some good deal with Mercedes so actually it's cost effective? And either way, the state are hardly giving away luxury items and that he should wind his neck back in.
Anything else I should know?
