Well, after a pretty stressful week (I hate car shopping) I am now the proud owner of a 2001 Ford Focus. It's the ZX3, which is the 2-door hatchback model, like Gloria though a bit larger. I named her Iris for the eye association with "Focus." She's blue, which can be a good eye color, and her interior is gray, which fits more with the color of the word "iris" itself. So I think it'll work. I kind of feel like she might need a last name too, but I haven't thought of one.
She has very low mileage (about 68k) and is in pretty good shape with most of the things that matter. Fairly new tires and brakes, other maintenance up to date, etc. There are some dents and scratches on the side and bumpers, but that concerns me less as it's more just cosmetic. The interior was a bit dirty and dog-hairy, but I took it to a car wash and got it a thorough scrubbing, which took care of that. I'm pretty happy about the sound system, which is all wired up for an iPod -- no more extra cassette adapters or power cords! And with all that, the price came in about $1000 under what AAA gave me, and under what some of the other Focuses I had looked at were running for. Good deal.
Update: I had been lamenting the fact that Iris didn't have a theme song the way Gloria did, but then I realized she actually does. "Iris" by the Goo Goo Dolls is one of my favorite waltzes (with pivoty zweifacher bits in it, no less). Yay!
