Contemplating the purchase of a new 2006 Sierra 2500 4X4. Would appreciate any comments on these vehicles especially if there are any major problems that have been noted.

Thanks,

I would recommend the Vortec Performance Package or the Sierra Performance Edition. I believe the Vortec Performance Package is available in the Heavy Duty or Light Duty Trucks. Or if you want a Diesel opt for the upgraded Duramax 360hp and 630lb torque.
