Which Audi are you comparing? If it's the A4, you'll find it's space as lacking as the BMW. These are all nice choices though. Also, as nice as the C-Class is I think that one will be smaller as well and if Front Wheel Drive is important to you the Mercedes will be out of the running.
For the money, it's hard to beat the Saab. The resale predictions may be reported lower but remember those are based on Sticker price. You'll do MUCH better than Sticker on the Saab.
Our 2002 Wagon is our second 9-5. We had the first year 9-5, tested out several competitors for it's replacement but just couldn't pass on the Saab. No regrets here, we love ours.
I had a '01 9-5 Wagon (SE V6). That model has been updated in '02 and renamed the ARC. However, it is basically the same car (with ESP and 5 spd. auto). The car was great. I use past tense because I was broadsided by a cadillac doing about 60 MPH, and walked away from the accident.
We purchased a '01 9-5 Aero in December 2000. The car is not even two years old, but has already had the following replaced -- DCI, Water Pump, info display, catalytic converter and several other parts. Most recently the car makes a "clunk" on start up. Has anyone else had trouble with the 00 Aero Wagon, or do I just have a lemon on my hands?
I purchased my 2002 9-5 Aero Sportswagon at the end of February, 2002. Fortunately for me, my area did not receive any further significant snowfalls that winter. Now, entering this winter driving season, the car has 6,000 miles on the original tires and I'm wondering if anyone can give me some advice on the need of snow tires for this car. Are they suggested, despite being a front wheel drive car? Being 17" wheels, the major tire stores (Tire Rack and Tires.Com) offer conflicting advice as to size. One says 16" wheels are fine, the other says that 17" are required due to the need for brake clearance.
I'm at a loss on this important issue since my area, the Pocono Mountains region of Pennsylvania, sees its fair share of snow each year.
Btw....I love this car. No problems to speak of at all so far.
I don't have an answer to your question but I do have a suggestion.
Check with your Saab dealer about any Specials Deals on a winter tire package. I don't have an Aero so it's not a big issue for me but our dealer does offer a program that is very competitive with extra service. They provide Snow tires on a Steel rim and they store whatever set your not using for you at no extra charge.
It's certainly worth a phone call. Also, I'm sure you already know but if you are doing this yourself, don't forget to use a Torque Wrench when mounting your wheels. Some people don't realize the damage that not setting equal and proper torque specs can do.
Saab and Ronal (OEM wheel maker) both offer snow tire packages that include alloy wheels. Both are competitive in price, and both recommend using 15" or 16" wheels as winter substitutes for the 17" Aero wheels, due to potholes and other winter road hazards.
Go to Saabnet.com, search 'snow tire' or 'ronal' and you'll see tons of posts on these subjects.
