That looks like 5.52% APR, not bad for sure. I did get a little better deal (ABOUT 2.67 APR) but it was a rare deal the more I look around. Here is mine:
Car price 42,495
Residual/buyout 24,520 57%
36 months @ 485
(12,000 miles/year)
Cash down 4,000
Total Payments 17,460
w/buyout 45,980 (if paid in full by end of year 3)
