Reduced blokes repairing vehicles with more than one level (6-7)

I believe the answer is:

double-deckers

I'm a little stuck... Click here to teach me more about this clue!

'vehicles with more than one level' is the definition.
I can't tell whether this defines the answer.

'reduced blokes repairing' is the wordplay.
'repairing' is an anagram indicator (the order is repaired).
'reduced'+'blokes'='reducedblokes'
'reducedblokes' with letters rearranged gives 'DOUBLE-DECKERS'.

Can you help me to learn more?
