Man, you can't go wrong with the Civvies....I have an 8 year old one (EX 2 door 5 speed) with 85,000 on it, and I STILL get 40-42 mpg on the highway (cruise-control, 65-67). On vacation trips, I used to be able to fill up and drive close about 430-450 before the light would come on. I can still go about 420 now.
One year I went to North Carolina, had the A/C on the whole time, and a mountainbike on a Thule roof rack the whole ride down. I got about 38 that trip, both down and back.
Around the city, I get about 22-26, depending on driving style and weather.
One downside is that after 8 years, it's like the car is suspended on 4 very large fresh marshmallows. handling and cornering have gone to crap, and it's not the tires' fault. I'm thinking about getting a moderate after-market suspension on it now, just to firm it up. 5 mile daily commute through pothole city streets killed those shocks and springs.
Only problems in those 85,000 miles is that the exhaust system rusted out at about 65,000 (known problem with that model year, actually) ...and the FACTORY Battery had to be replaced last year. Factory tires (freakin Dunlops) lasted to 68,000, before they started to fail the penny test. Belts are starting to slip a bit, but those are gonna be replaced around 90,000, which is I think what the manual recommends.
Seriously man, take a good look at the civics. There's a reason why the resale is usually so high, and most owners hold on top them until they need to upsize (such as work or a growing family) or they're totaled. They just work, and work well.
Added:...I do know my cars and performance handling...I went from a '96 328is Sport Package BMW to the Civvie....lost a lot of performance and handling, but the trade-offs weren't that drastic. Insurance dropped $1200/yr, and I didn't have to worry about the neighbors dinging it out of jealousy. Also went from 31 MPG tops premium to 40+ MPG regular.
