I have a 2008 Honda Accord v6 Couple, 6 speed manual.
It has a nice, tight ride, handles well (but it is a pretty heavy car), has lots of interior room (back seat is awkward to get into), but the gas mileage is only about 26 on the highway.
Performance is very strong. With the traction control turned off I can smoke the tires through 1st, 2nd, and part of 3rd gear. A second gear roll-on will smoke the tires, also. The engine is very smooth, with a sound like a muted Honda F1 engine (which is kind of what it was based on). Fit and finish is top notch. The leather seating on the EX-L trim is supple. Better than my 2005 Accord was, and 10 times better than my 1993 Bonneville.
However, no car is perfect. Being a front wheel drive car it does understeer when pushed hard in a turn. Also, the shifter is not as firm-feeling as a rear wheel drive car(since it's got longer linkages to the transmission). Gas mileage is not great. Expect 18 city, 26 highway. My mixed driving gets about 23.5 mpg. Of course, I am not gentle on the throttle. My car had a few issues: the worst was a balky 3rd gear synchronizer. Also, the 3rd brake light had some rattles along with the rear hat shelf due to the subwoofer when playing bass-heavy music tracks. The stereo has a great sound, though. Very good highs and lows. Headlights could be better, but switching to those ultra white bulbs might help.
Climate control system is top notch, will hold temp nearly perfectly even on the hottest days. Seat heaters, however, are slow to warm up in my opinion. The GM cars I have driven warmed up faster. Rear window defogger is also a bit slow, but the mirror de-icers are great. With the sunroof and windows down, buffeting is not bad even on the highway. With all windows closed, the car is quiet, except for road/tire noise which is a bit loud. But all of my Accords were that way.
Basically, I love my car. It's easily the best car and best Accord (I have had a 1999, 2005, and this 08, all coupes) I have ever owned.
