Personally, I wouldn't get a 2004-2005 model...there were many electrical problems and such, apparently. But I just bought a 2006 Honda Accord Hybrid off Craigslist for $20,500 (one-owner; no dealer fees for "window tint", "undercoating",etc.). I changed out the nerdy-looking wheels - had some people at an Import Auto shop get me 4 stock 2006 Honda 10-spoke sport wheels, then the front calipers had to be ground down a bit at the tire store...but it was only a minor modification. Now it is sporty looking, but not "snooty"
It is an engineering marvel! It is a MUSCLE CAR! (a teenager raced me the other day in his Mustang, and I blew his doors off). It has sound-dampening, takes regular gas, gives you a tax rebate, 4-doors for the family, out-accelerates the new 2008 hondas (and quieter), with better fuel mileage than similar acceleration cars (BMW, Mercedes, Lexus), and takes "Regular" gas (unlike Nissan, Acura). Light sport suspension and steering give it a sports car feel...good visibility.
Some people are unloading theirs due to a complex problem with the brakes, that continue to develop air in the lines despite changing the master cylinder (like in my case). The defect is a Control Module for the ABS Anti-lock brakes (covered for 2nd owners under warranty if under 36,000 mi). Brakes are good now that its fixed (even though Hondas don't generally have great brakes) - the ABS kicks inn a little too easily; watch your speed, it will drift from 90 up to 110 without even breathing hard.
