Any sticky buttons, any leaks under, rattles, check coolant tank for any cracks known issue, mine grenaded on me while driving. Make sure trunk button in cab works as well as pull handle behind driver seat to the right of passenger seat bottom make sure both work. Check both sun visors make sure their not drooping its a son of beep to fix, check date of battery also check if car is missing factory battery tender. I would go over every damn fuse in car these things like to eat fuses and check alternator because I went through 2 Already your dash will light up like a Christmas tree... Make sure radio is functioning correctly believe it or not it can disable the car and believe me you don't want to know the price of a new radio.. mine went bad because of the hard drive built into it and because their software that's hardwired into the car's ecm. If I can think of anything else I will update this is my second GranTurismo had a 2009 f1 sport now I have a 2013 mc sport with the zf tranny... I'm no expert but I know a little bit of some issues I went through..
Here's some before and after of what I got going on.
