"Let's take a hypothetical approach (keeping it modest).
+$42.654.60 purchase price of the car
+$ 56.50 Title and registration & transferring plates - $12,796.58 30% down payment / trade in value
$29,914.52 Amount financed (70% of the sale price) for 60 months @ 7.00% -$592.34 "

One small change to the above if that car is purchased here in AZ the tags and reg will approx be $750 the first year and be slightly reduced every year there after.
