Tom Anderson gurgled happily, sounding much like
they were saying:

Although probably not in the Yorkshire colours (may have been less
garish).

Unlikely. Green battenburg's fairly standard for ambulance service
nationally.

Paragraph 4.10 in the report Mr Smyth posted says:

The 4 x 4 vehicle was marked clearly as a paramedic vehicle in bold
red and green colouring

And also that it was a Honda CRV, like the one in MIG's picture.

Red and green sounds horrible.

Indeed.

One Cambridgeshire/East-of-England ambulance service Honda CRV fast
response vehicle...
