No, it isn't.

That's a VW Touran mini-people-carrier. Not only isn't it a Honda CR-V,
it doesn't even have a white bonnet as you claim - that's silver.
Really, Roland, you do seem to be determined to make yourself look an
utter tit in this thread.

This is a Honda CR-V, in ambulance livery.

Blimey! That looks JUST like an ambulance!

Is the word "AMBULANCE" on the bonnet a clue? Just like, with the VW
Roland posted, the word "PARAMEDIC" would be a clue?
