In Mexico, there’s not much of a market for classic cars and most surviving examples no longer have their original engines or have been extensively modified in various ways. If you wanted a useable, fancy looking 50s/60s American car to cruise around town in, you wouldn’t need to pay more than £5k and probably quite a lot less if you weren’t fussy about the model or it’s originality.
