I was passed three times today by the same Honda Odyssey van. Two times, I pulled up beside the van at the next red light, and once I ended up three cars ahead due to the traffic pattern at the light. Apparently some people just have to get to the next stop first. I'm more of a steady driver and go with the traffic rather than trying to beat the traffic.
The Fit is suitable for me on numerous levels--storage options, mpg, insurance rates, initial cost, parallel parking in downtown, plays well with a hitch-mount bike rack but also carries one inside if needed. I recognized the slight demerits for long trips on the freeway (I take 4-5 per year) and slower off-the-line power (I don't drive that way anyway) and matched them against more powerful, sporty options (sport hatches in my case). In the end, I found out what mattered most to me and went with that. No regrets thus far.
Also, for the most info, google the Honda Fit and Honda Civic user forums. Plenty of the goods and bads of each model there with individual comments, reviews, raves, and complaints.
Good luck!
