2004 vs 2008 Saab 93 Aero?
 

Hey guys! Thus is my first post! I'm really interested in purchasing a saab for my next car.
The two cars I am consider are -
2004 SAAB 9-3 Aero Sedan Automatic 88K miles Silver
and
Used Saab 9-3 For Sale Chicago, IL - CarGurus

The one from craigslist has 88k miles, was very well maintained, and the owner is selling it because they had another child. It is 2004 and the price is $7800
The one from cargurus has 45k miles, and costs more. It is a 2008 and it is an aero model.

Which would be better to purchase? I want one with the best fuel economy, and will cost the least to repair and maintain.
