I have quite a mix of dashes that I like. I generally agree with you guys who like simple, "thin" steering wheels. A classic wooden Nardi is pretty much my ideal steering wheel. I hate steering wheels with massive centre bits and huge collections of buttons.
I like minimal things, so I must say the Tesla Model S dash is really nice to me, probably one of my favourites. Really clean looking:
The clean lines are great, and although the steering wheel is pretty chunky the clean design keeps it looking slick.
I also like things like the BMW 2002 interior, simple and nice, a bit of wood here and there certainly improves things
(better with a manual though)
I'm not such a big fan of modern interiors with a million buttons on the dash and trans-tunnel. Gets a bit overwhelming. I also find a lot of dashes a bit too "swoopy" these days. I dunno. I do like the trend of circular HVAC vents though, e.g. the new Jag XJ comes to mind and Merc SLS. They looks pretty neat.
I drive a Fiat 500 currently, and like that interior quite a bit. It's simple, of course it's a cheap car so materials aren't great, but the steering wheel is wrapped in good leather, and what buttons there are a really well integrated. Here's an old pic of mine - rare (discontinued) colour combinations going on:
Excuse the out of focus photo.. I never did get around to taking an in focus shot.. should do that before I move on car-wise...!
