Hello everybody.
Im from Toronto and wanted to introduce myself.
I Like fast 4-Door sedans, I really do. I currently own a 2010 Chrysler 300C SRT8.
Its a great car and a looker aswell. here's a list of mods:
* AFE CAI
* Tuner CHIP
*22' RIMS
* Coilovers (with 2' drop)
But Time has passed and I wanted to make a change. I figure an E60 M5 would be fun and very different than what im currently driving.
I was hoping someone could help me. Im thinking about a 2008 that is pictured here:

It has about 91000kms, looks great and the interior Leather is good as well.
It has some obvious Mods:
*Lowered suspension
*Dual CAI
*Murdered OUT 19' wheels
Im planing on taking it to RMP motors for a pre purchase inspection.
The Question is: There are a couple of extra unlabeled buttons in the car and I was wondering what they would be for?
A small Black button just above and to the Left of the shifter:
and two switches under the steering column:
I ask the Sales person he doesn't know and not surprisingly does not allow me to talk to the previous owner about it. Im thinking it might be for a police radar scanner but I dont think ouy need a button and 2 switches to operate it.
Does anyone know what they are for?
Any help would be appreciated. as well as any advice for a hopeful soon-to-be E60 M5 owner.
