I bought this car in 2006 and have been driving it since then. It has 153,000 miles and runs great, it had 88,000 when I got it. It has never broke down, and has needed minimal maintenance. Overall it has been a great car.
Hypermiling, grill block, rear spoiler and wiper delete, antenna/antenna motor delete, 55psi in tires, Mpguino. I also use Pennzoil Synchromesh in the transmission, probably doesn't improve FE, but this stuff works really good in Honda transmissions, might want to try it if you drive a Honda.
I plan to install an air dam, and maybe at some point a full under body.
