Value of a 2013 M6 Convertible

[mjposner]

I am thinking of leasing a new car (need more tax deductions), and I am trying to get a feel for the value of my M6.

It is San Marino Blue over Silverstone Leather (not extended).

45k miles. 19" wheels

DCT, B & O Stereo, Night Vision, Nav, Comfort Access, Heated Seats/Wheel, cooled seats, no accidents

I have updated the nav maps to 2016, coded for no legal warning and dvd on the move, changed shift knob and wheel inserts to carbon fiber.

I also have an escort laser jammer with 9500 redline detetector, and custom sub box in the trunk that I will remove unless the price is right.

Has Platinum warranty to 10/18 or 70k miles (which I can cancel and get a partial prorated refund).

Front tires only have 5k miles, needs new rears.

Thoughts?
