Changing brake pads is a breeze, although it's not too difficult on most cars. Accessing spark plugs is also a breeze, although I haven't replaced them yet.
The cabin air filter is behind the glovebox, takes about 5 minutes to get out and is good to replace occasionally, as ours picks up a fairly large amount of debris.
The engine has fairly horrendous piston slap for the first 10-15 minutes of driving, and has for some time now. I'm unsure as to how it will impact engine life. I do hear many other V6 Hondas with similar piston slap.
Our lifetime fuel economy is about 22-23 mpg, which is mainly "around town" driving of under 40 mph with frequent stops and short trips (under 5 miles). On the open road, it averages 32-33 mpg at 65-70 mph and has done as well as 37 mpg over several tanks when I drove it to Pittsburgh a few years ago. I would consider the fuel economy excellent, especially for a fairly high horsepower engine (240 or so, if I remember right).
I spend a bit of time driving an 05 Accord. They do piston slap quite bad. But, I've seen (and test drove) a few others that do it too.
The 3.0 J series has got to be one of the SMOOTHEST engines I've ever drove. I'm just amazed at how smooth it is. And there's torque everywhere. It's not geared extremely low, but I've accidentally lit it up taking off from a stoplight. Going from either of my vehicle to that, it's hard to keep it at 55!
Not too happy about the timing belt, or the piston slap, though. I've heard that when the VTEC kicks in, the engine is like a rocket. But from what I've seen, it's perfectly adequate for even hard acceleration below 3500 RPM.
THey also do this odd thing engaging in drive, where it engages twice? They all do that too. The transmission worries me as they are a bit problematic.
Never able to push it past 30MPG, but I did get pretty close a few times!
