When they do the financing they get a kickback.
They basically took that kickback they lost and
added it to your car. Not sure if it's illegal, but it's
certainly unethical. Never go car shopping with one
model in mind, always know what the comparison
model is for other makes. Research the extra fees
they try to charge you. Never tell them what your
limits are in price or payment. Watch what you sign
and say, never give them permission to pull your
credit. Whenever they ask you those questions,ask
them a question instead of answering. Don't give
them your address, doc sec# or drivers license.
They can't pull a credit report without that info. And
if they say it won't effect your credit they are lying!.
Also the longer a car sits on the lot, the more it is
costing them. Also if you want a Buick enclave you
don't need to buy it from a Buick dealer, check out
the inventory of other dealerships for one. They will
probably give you a better price to get another make
and model off the lot.
