Front seat support & comfort
The interior is the Ridgelines stronges point. Comfortable front and back and a feeling a space. The lack of transmission tunnel and column mounted shifter in particular make the front cabin roomy.
Driving position & visibility
excellent, you feel your're sitting "up tall" like a fullsize truck. I changed to this vehicle after owning a fullsize GMC for several years which I loved. One of the things I enjoyed the msot was the interior. While the Honda is by no means a fullsize truck, the interior space and seating position are very similar.
Powertrain performance
No, a Ridgeline won't tow a big trailer or do well off-road, but the engine and transmisison are silky smooth in town and on the highway. The AWD system seems to work very well in winter conditions here in Anchorage, without the standard tires. The center differential lock (or electronic system that simulates one) is helpful.
Controls and instruments
Everything is where is should be and works just right.
Cargo capacity
It's go plenty for the average home owner like me. At first I thought the underbed storage compartment was no big deal - I use it all the time.
Quietness
If you know anything about Honda's you know this is a problem across almost every model. The Ridgeline is no better or worse than any other Honda in my opinion. Engine noise is not a problem, wind and tire noise really can be on the highway. Thankfully, audio system (mine has the subwoofer) does a good job covering it up. The ride is great under all conditions.
Exterior styling
You either love it or hate it.
I avoided buying a Ridgeline for years becuase of it's looks and because it's not a "real truck." After trying (bought and sold in less than six months) a SportTrac, I bought one. I love it. It fits my needs well: four doors, fits in my garage (necessary in Alaska) and has a spacious comfortable interior. The other need is for a combination AWD and 4WD system for the winter driving here. The AutoTrac system in my GMC Sierra was perfect, but there are very few pickups (that would fit in the garage) with a combination AWD and locking 4WD transfercase. The Honda system is a compromise on that, but you can't have everything. It's capable enough for my weekend runs to the lumber yard (okay, so if I need 12footers I'd have a problem) and garden center.
