Schaumburg Honda

I wanted a rare car and have been looking for months. When i saw a new one pop up at this location i asked if the price included everything and honda certification as it was 6 months used. I was told yes it is. I drove 40 min and when i liked the car we talked finance. the first thing the sales manager does it pull up the price i saw, adding $3K in accessories and $1.5K for honda certification. I told them to remove some of the accessories. They used typical car salesmen pressure tactics and i agreed to pay $2K more than my walk away amount. but at least we had a solid number. When i am filling out the finance paperwork i notice it is $4K more than agreed. the finance officer said it was because they were "required" to charge for the 10 year extended warranty. after threatening to walk out they reduced it to $2.4K. then i started putting on my coat. finally the waived it. i was supposed to get a $12.5K cash check back for my trade in. they charged me $155 because title was still in Honda's name. no where in my entire paperwork does it say they will charge for that. but they took it anyway. they told me they would get me the best loan. they got me 5%... i am assuming because they get points. So i am refinancing, already approved for 2.75%. I am hoping if i refinance immediately, it will cancel their commission.
