This is my second Element. My first one was a 2006, same equipment, different color and traded for an S2000 which was fun while it lasted. I use my 2008 Element as a daily driver and I also sell a high-end Swedish car in my day job which I know inside and out (this will explain some of my suggestions later on). I think the Element is the perfect vehicle for me for a lot of reasons. It gets reasonable gas mileage (27 highway, 24 overall), it has reasonable power, is a blast to drive (no S2000, but what is?), is reliable as motor vehicles get, and has great ergonomics and fun to drive.
Versatility, plain and simple.
Automatic audio control for sound output to adjust when noise levels get higher, powered rear windows and moonroof, AC control knobs that look more like the audio controls (current ones look tacky), and maybe a diesel engine.
