Cheap rhyme for a jalopy (4)

I believe the answer is:

heap

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

'for a jalopy' is the definition.
('heap' can be a synonym of 'jalopy')

'cheap rhyme' is the wordplay.
'HEAP' is hidden within the letters.
However, I'm unsure how this is indicated.

Can you help me to learn more?

(Other definitions for heap that I've seen before include "pile-up" , "Unreliable old car" , "Wreck of a car" , "Mound - dilapidated vehicle" , "Rough pile" .)

I've seen this clue in the Evening Standard.
