I will use your car as an example if I would have bought that. Lets take off the 19's off ($1,500) so the price is $54,200 and has AP where I paid $61,500 with EAP (Summon/auto park) That is a $7,300 upfront difference.
I got a $3,920 tax deduction where you got $3,750 so that is $170 in my favor.
I will own this car for five years so lets look at taxes and registration. The different in the $7,300 is $511 ($7,300 * .07) in taxes and $711.60 in vehicle registration. Total: $1,222.60
My Total: $61,500 - $3,920 + $1,222.60 = $58,802.60
Your Total: $54,200 - $3,750 + $0 = $50,450
Difference: $8,352.60
