Considering $0 drive-off this is not a bad deal. You can do a little better if you put max 9 MSDs ($500 x 9 = $4500) and your interest rate goes from 2.4% (MF .001) to 0.67% (MF .00028), approx $50 less per month
Did you move on this deal that Santa Monica Lexus offered you or did you do better elsewhere? Was this quote their first initial offer to you or did you had to haggle to get that selling price?
Is it possible to get this deal now from this or other dealers? Selling price is pretty good.
