The MSRP for a LT1 is $24,730, I usually add in a couple hundred for fees, title, and registration. So you go up to $24,930. Then you need to add tax, for me it's 1.08% so it then goes to $26,924. Now you subtract your down payment, I'll aim low at $4,000, now you're at $22,924. Now finally add in the interest rate, I'm not sure what you are going to get but let's say 6% @ a 5 year loan. Your monthly payment is going to be $443.19 with a total payback of $26,591.
I didn't pull any of this stuff out of thin air I used a ammortization calculator like the one
here.
Hopefully this helps
