2.0's show up all the time. I found 10-15 last time I looked. Unless you're keeping an eye on the 9-2x board, the only '06 Aero you usually see is an auto, which is rarer than a stick.
Got the same mailing from Saab. Just need to find the time.
2006 (1,832 cars produced) US
Aero 5MT 235 16.17%
Aero 4EAT 103 7.09%
I would expand your search to 04-07. Some websites list the car as being sold under those model years.
Funny, a guy pm'd me out of the blue about a year back about selling mine, and wouldn't take the hint. Just kept sending messages. This was another board though.
If you can find one, they are great. I daily mine and last fill up got 26.3 MPG. Helped the girlfriend in moving last summer with zero issue, I was really surprised how much the car can hold.
Pros: Comfortable, decently fuel efficient for a Turbo AWD vehicle, spacious interior, heated seats.
Cons: Stereo, worried about sourcing the Saab specific body parts.
I'm sorry if that didn't flow well/make sense, very tired. If anyone has any questions about the 9-2x or even want to take a look at mine (even though it is dreadfully dirty right now), I usually try and make it out to sawmill or just shoot me a message.
