Not the person you were responding to, but I figured I would give my experience financing through Mark Dodge when I purchased a few weeks ago.
My credit score was high 700s.  With $1000 down (the deposit on the truck) on my ~$60k purchase price, I was offered a 3.5% loan for 60 months.  Putting an extra $10k down ($11k total), that dropped it to 1.95% for 60 months. 
If you don't take any special financing from Chrysler Capital, Mark Dodge's rates seemed competitive.  The 1.95% is lower than what my credit union advertised.  I ended up taking the 0% for 48 months, though.
