The seats are supportive and comfortable. The leather-wrapped steering wheel fills the hand just right. The outside mirrors are remarkably large for a sedan. That's a feature SUV drivers often mention as a reason they like SUVs. Here are large mirrors with an informative view of the world behind and yet add no noticeable wind noise.

Initially we thought headroom seemed a little tight, but the Grand Prix offers more headroom than a Honda Accord. One of our few disappointments was the glove box lid, which opens with the clatter of plastic.

The instrument panel, pleasing in its three-dimensional, yet simple, layout, is readily visible through the smart three-spoke steering wheel. The large center speedometer stands out from and overlaps the tachometer (on the left) and the circle containing the fuel and temperature gauges (on the right). Backgrounded with a shadowy grid pattern, these watch-like dials yield their information with simple, uncluttered, handsome functionality.

Technology allows the speedometer to be rimmed with only one set of numbers to designate speed in both miles and kilometers per hour. How? Punch in your choice on the Driver Information Center (DIC) and the numbers change. Cross a border, make your selection and read Ks; punch again and it's miles. No cluttering inner-ring of numbers. How cool is that?

You'll find the optional head up display (HUD) almost subliminal in its presence. You can select the amount of information it gives and at night, to conserve your night vision and limit reflections, you can douse the instrument panel lights completely, fly in stealth mode, and still keep tabs on what's important.

The Driver Information Center with its four-line read-out is just to the right and above your fist in a console canted slightly toward you. Below an organized cluster of white icons on simple black buttons and dials keep the driver tuned in, warm or cool, etc. Pleasing to look at and nothing bewildering.

As comfortable as the seating, as pleasant to look at and feel as the interior is, what is really special is its functionality and flexibility. Not only do the back seats fold down in pairs or singly (with a 60/40 split) to effectively increase cargo capacity, the back of the front passenger seat folds forward (on GT and GTP), table flat.

All this flat and nearly flat space can be accessed through the trunk (with a particularly low lift-over height.) Thus it's easy to fold the appropriate seats and load long objects into the vehicle: a roll of carpet or a ladder or skis or Italian market umbrellas. You can close the trunk door on anything up to nine feet long, like a rigged fly rod, for example. That trunk opening besides being lower is also about ten inches wider. Boxed bikes anyone?

With the rear seat up and five people on board, the trunk still holds 16 cubic feet of whatever those folks need to carry.

Lots of interior toting room is worthless if you can't get the objects you are toting through the holes in the vehicle. In shopping mall parking lots anywhere in the country you'll find cartons that once held TVs, microwave ovens, computer components and barbecues. The products had to be stripped of their packing to manipulate them through car doors. Cognizant of that problem, Grand Prix designers played dentist: "Open wider, please." And now the doors swing out 82 degrees, improving ingress and egress for people and stuff.

Driving alone may not be an efficient use of fossil fuels but the fact is most cars most of the time carry only a driver. The solo driver can particularly appreciate the fold-flat passenger seat: it's a veritable desk at the elbow with indentations to keep coins at hand and a webbed elastic pouch to keep such things as mail ready for the slot from finding the floor at the first stop light. Or have you an unlucky skier in the family? Put him in the back seat and rest that cast-clad leg on the fold-flat front seat. Mobility in luxury.

OnStar is now standard on all Grand Prix models and features new, sixth generation hardware for more intuitive continuous digit dialing and improved voice recognition accuracy. OnStar provides core safety services and OnStar Personal Calling that allows drivers to make and receive hands-free, voice-activated phone calls using a powerful three-watt digital/analog system and external antenna for greater reception.
