On my carrera t I honestly didn't care that much about RAS since it still was relatively a small car. My question is for a Cross turismo 4 if it is necessary since its a decent sized car. Is PTV worthwhile? I figure it's not that powerful a car so why get it, or maybe since an AWD not powerful car if it will plow without PTV. Leaning towards just RAS, but have there been any reliability issues with it?

 

definitely RAS I buy it all my cars now. I can't say I ever noticed PTV is any of the cars I've had
