Since you fuckers can't figure out the back story on the Garcia's new car, let me lay it out for you ...
Mr. Garcia has been laying the pipe to neighbor lady for a LONG time. Mrs. Garcia (who we never see because she's pumped out 7 kids and looks like a shell of the woman Mr. Garcia actually married) is totally clueless because she's busy shepherding around Mr. Garcia's spawn on a full time basis.
Mrs. Garcia, who thinks that neighbor lady is a friend as opposed to her husband's side piece, has been bitching to neighbor lady for months about the fact that Mr. Garcia can't get it up for her.
So, when neighbor lady sees that Mr. Garcia bought Mrs. Garcia a middle of the road pseudo luxury SUV she, in a moment of introspection, takes some solace in the fact that even though she's making hot sweet love to Mr. Garcia on a consistent basis, at least Mrs. Garcia got a new car out of the deal. Hence, "good for her".
Oh, and Mr. Neighbor keeps the binoculars handy because he wants to be prepared in case there is a chance of him spotting his lost soul or crushed dreams.
