How reliable is a Volvo XC90?

I’m thinking about getting a Porsche Cayenne because I love the power and features, but I need the convenience of an SUV. I know that it might depreciate, and this will play a role in whether I buy new or used. How much does a Porsche Cayenne depreciate over time?

My daughter and her friends built a float to represent their high school in the Santa Claus Parade and she volunteered to drive it without knowing anything about the towing capacity of our family’s Subaru Impreza. Before I go out and buy a tow hitch, I have to figure out if our car can handle this. How much does an Impreza weigh?

I just took my 2008 Infiniti G35 to a repair shop because the car wasn’t accelerating as quickly as it usually does. They told me it would cost $1,800! Does the 2008 Infiniti G35 have ‘catalytic converter’ problems? And how do you tell if it does?
