Collectors, take note: Saab has brought out some very limited production versions of existing cars.

For example, just 500 units of the 2007 9-7X Altitude Edition will be produced for the coming sales year. Among its special features will be 18-inch alloy polished wheels, side assist steps, a rear DVD player and an exclusive carbon fiber gray metallic paint.

What's even more attractive is that all of these items in one package will be offered at a total savings of almost $1,000 over the cost if you'd ordered the items separately -- though you're still talking well over $40,000 for the car.

There are other changes and additions to the 2007 9-7X lineup. On-Star equipped models have a new service called OnStar Turn-ByTurn Navigation, which is the first factory installed fully integrated GPS navigation system from OnStar. The system lets consumers talk to a live adviser who, in turn, sends complete step-by-step direction to the vehicle through the OnStar system. Other 2007 changes include a standard tire pressure monitoring system and a new color, Crystal Blue metallic.

For the 9-3, the biggest change clearly is the new interior and dashboard. I've always loved the 9-3 but found the controls to be problematic. They are not always where you expect them to be, particularly for the audio and climate control systems. I haven't seen the new design, but I'm hoping for the best.

Available engines for the 9-3 range from a 210 horsepower turbocharged four cylinder to a 259 horsepower 2.8 liter V-6 that gets 250 horsepower. Mileage ratings are around 23 city/34 highway and prices range from $26,620 to $42,620.

The 2007 9-5 was given a Cinderella style makeover last year, so it's pretty much holding the line on big changes this go-round. The engine is a 2.3 liter 260 horsepower I-4 rated at 21 city/29 highway.

The 9-5 will get a special Anniversary Special Edition later this year that will have Ice Blue metallic paint, a specific leather interior and 17-inch wheels. Titan Gray metallic replaces Steel Gray metallic on non-Anniversary models. Prices begin at $34,820 for the 9-5.
