I agree that no dealer should add 3%, thats totally ridiculous. Now a half a point or so I can understand. I am new to selling vehicles, just coming up on a year. I've been with the same dealership the whole time, and I guess I haven't been exposed to the shady dealers out there.
My own bank quoted me 6. 9% for a loan on my last used truck, my finance girl got me 5. 9% from the SAME freakin bank!!!! I went with another bank that gave me 5%. My original bank called me a few days later, asking if I was going to use their loan, I said no. They replied, "well, we could of worked with you on the rate"
BTW, we charge a $100 processing fee, not $150-$300. It has a little more to do than just finance. The paperwork goes from my desk as a sales consultant, to my finance desk, then my sales manager's, then my general manager's. Then of course it does out back to our admin building, where it hits 2-3 more people's desk. So $100 isn't crap when you consider.
I am just stating all these facts to let you know their are dealers with integrity out there, and i happen to work for one.
I could go on a rant about the deceitful practices I've seen customer's use, but that won't get us anywhere.
