ideas for an 89 300SEL?

[hedpe]

Hey guys, i'm currently looking for suggestions on my 1989 300SEL, from systems to lights to anything! It's currently pretty much all factory. My only addition to it is my laptop which i place on my passenger seat when i ride alone, use a car kit, and play some mp3z, also got a GPS receiver to hook up to the laptop to navigate my always lost self. I was looking in to a mount like the police cars have for laptops, anyone know of good ones or suggestions?

Here she is:

(yes the passenger side headlight wiper is messed up if you know a solution I started a post about it in the tech section!)
