The only issue I have with the GB200 is that the foglights don't work. It triggers me, especially for a rally/rallycross/hillclimb kind of car. Otherwise it's a great ride, nice acceleration, average top speed (but who needs top speed in rally tracks), a bit twitchy but very responsive.
GB200 is VERY hard to handle off road. It tips over alot similar to the Kuruma. My suggestion would be the Tropos, to me it is the easiest to drive for rally. I think it's comical when people pick non Rally cars for rally racing. BTW the Jester is one of the worse traction loss on dirt,also the engine dies on diet.
All I have at the moment is the Armored Kuruma, though I'm thinking of getting a more proper rally car in the near future: the Omnis or the Tropos perhaps. I heard the new GB200 is pretty good offroad, though I don't know if the price tag makes it worth buying. Does anyone know how the Comet Safari is to drive? Might consider that as well to buy.
The Comet Safari is similar to the Kuruma. Nice straight line speed, great traction loss difference. BUT the issue with both is it rolls over rather easy. Safari is not as bad but not as fast either. Honestly in a racing crew with non randoms you are going to be hard pressed winning with a Kurumas due to the stability of the car rolling over on turns and bumpy roads!
I would pass on the GB200 if money is an issue. Go with Tropos IMO
