 I work in the car rental business, so I often change cars that I use as company cars.  My previous car was the Pontiac Grand Prix.  The V4 engine is a bit sluggish with the acceleration, like there is a delay when you floor it.  But when you get it up to speed, it performs great and you are very comfortably at 80 mph.  The breaks are great right off the bat.  I'm not sure if it has traction control or not.  If it does, it's not great.  So it's a bit tough to accelerate from wet pavement.  I have previously driven the Nissan Altima as a company car and I'm not sure why it's hailed as the category leader.  It's nosier than the Galant, feels much lighter and flimsier.
