Door repaired with deal in wealthy place (8)

I believe the answer is:

eldorado

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

'wealthy place' is the definition.
'Eldorado' can be an answer for 'place' (mythical golden city). I am not sure about the 'wealthy' bit.

'door repaired with deal' is the wordplay.
'repaired with' indicates an anagram.
'door' anagrammed with 'deal' can make 'ELDORADO'.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for eldorado that I've seen before include "rich land, so many thought" , "source of wealth" , "city, apparently lost" , "wealthy location" , "city of riches" .)

I've seen this clue in The Sun.
