I had a 2000 Ford Focus up until October. I drove it until I couldn't drive it anymore.
-Gas mileage is good. I averaged 30-32/mph
-Engine life is dependable. I got over 208,000 on it. I could have gotten longer, I'm sure, had I known what some of the signs at the end.
-Good storage space for a car... spacious trunk, back seats that fold down
-A little bumpy in the handling, not the smoothest car out there, but good for the money and I got used to it quickly
-Never noticed any problems with transporting large people in terms of seating and room. I used to work with some overweight women (one who was particularly tall) and we never had problems as far as getting in and out of the car. It did handle differently once they were inside, but I think that is part of "carrying the load" as it were.
When my car finally gave up the ghost, I tried the 2009 Focus to see if I'd like it, but I didn't. It's still a good car, but the changes in design no longer worked for me. I went for a Pontiac G5 instead. It's just me, and I don't have to worry about toting equipment or family. So I went for the sports car-lite.
