The cars.....well the Aventador isnt all its cracked up to be, it looks great, but its not that quick in a straight line, in the corners it feels really heavy and sluggish.
The Beetle is cool, creates some great pictures and is good fun to drive.
The Nissan Leaf is just a joke.
Countryman is as Toronado said, a heavier, uglier, slower Cooper S.
The Jag we already have as a standard, the only plus side is you can take pictures in the locations with it.
The V12 Vantage is great, sounds awesome, looks amazing, and drives beautifully. Really love this car.
The track is incredibly boring by yourself, the speed testing thing is flawed (Ellis see my post in the FGTC

) However you can take some incredible pictures, and it will be good for some dirty nascar racing.
