the 175 hp engine was available in 2003-2005 on the Linear only (the Arc, Vector have) the 210 hp used in the 2.0T through 2009. The 175 hp engine is commonly called the 2.0t.I love my 2005 but I'd suggest getting an 06 or 07 as the four cyl has 210 hp while 04 and 05 have 175.. a $1000 tune to get an 05 to 06 specs.
I'm not sure how your market is, but sounds like a fair price to me (provided everything is ship shape with the car). As always, I would start a few grand under the asking price and go from there.I too am in the market for a 2006 9-3. Black with grey leather - 50k miles. asking $11,000. Good deal or not?
