Any way you slice it it is going to be a lot of work to replicate the same functionality of those sites which you have shown with any generic CMS. Working on a very limited budget it would be best to use a CMS specific to the business goals at hand. That is if one exist specifically for vehicle listings. Otherwise, you have a lot of work ahead of you working at slave rates from what it sounds like.
Famous last words.
