I have several friends of the Jewish persuasion who don't know squat about money...but then again neither do I.
It appears you have an uncommon and mutually beneficial relationship with your dealership...you get what your genetically predetermined sphincter requires (a good deal) and they get a loyal customer with many friends (who may not be so financially astute). Apparently, your dealer thinks that is worth giving you some cosmetic extras (?hair piece, face-lift?) and a good deal.
So congratulations, good luck with the financial biz, enjoy the Audi :)
