Teresa Giudice: $90k Welcome Home Car ... Broke, Reallly?

Teresa Giudice got more than a welcome home from her family ... a $90k Lexus was lying in wait in her driveway.

It's interesting ... Teresa and Joe were scraping money together just before she went in to pay the $400k in restitution.

We're told Bravo did not buy the car for her. We called around and we're told Joe was shopping for a Lexus from a New Jersey dealership specializing in luxury cars.

What's very clear ... the Giudices have already made some rich deals to capitalize on her release from prison.
