Cars

Renault Turbo 5   

But Caterhams a must for sure.

And if or when you want to try out some dirt racing with some awesome WRX cars (or many others work well in dirt too) you're in for a real treat...the dirt physics are fucken amazing to the point you easily get more grip accelerating out of the side of the track with less pot holes I kid you not. With a wheel and a 10 minute dirt race its quite the workout. The dust cloud behind the cars is truly amazing, much better than the DIRT series you literally can't see crap when you're approaching a car but if you get up close enough to them you avoid the dust cloud because you're so close to the car ahead it is simply awesome. One track is half tarmac, half dirt which you can race at night which is gorgeous. 

Snow is cool too.

The Deltawing is back.

I'm liking the prospects for rallying - lots of classic as well as more modern cars to slide about with - it'd make a nice change of style.

I guess karting round the nordschlieffe would be out of the question - we'd probably run out of petrol before doing one lap :P

Don't have the game BUT this did catch my eye...
