I have a 2005 model with 77,000kms on it (a few things have changed of course for 2006+)

Likes:

• roomy (in every dimension except shoulder room)
• versatile cargo area (fold flat seats can fit a fullsize mountain bike)
• lots of storage bins (inside the cabin and in the cargo area)
• Smart Key System
• compact in size (great for parking in tight spots)
• easy to drive
• EV mode
• fuel efficient (of course)
• location of speedo makes it easier to read without moving the eyes too far from the road
• 7" MFD (lotsa potential there for mods. backup camera, DVD player, playstation hehe)

Dislikes:

• a little low to the ground (2 people in the back and you gotta watch those bumps)
• crappy stock tyres (upgrade if you can)
• unsorted stiff suspension (doesn't feel as nice as other cars with a "stiff"-ish suspension such as the Legacy or the TSX)
• A tad noisy at highway speeds (I'm coming from a Camry which is quiet so that's my reference)
• foglights are more decorative than they are functional
• 9-speaker JBL audio doesn't sound as great as our 6-speaker JBL system in the Camry. I think the JBL's been upgraded for 2006+ models but I haven't heard it myself.

Mods: EV mod, VVT-i emblem, sport pedals, OEM cargo mat, JDM Prius interior footwell lighting, Sylvania Silverstars 9003ST, DICE iPod kit, OEM all-weather mats, TomTom ONE v2, LED licence plate lights.
