Fun to drive, very versatile, reliable, economical, and safe. 1. Fun: with decent tires this handles like a mini-BMW. Firm yet smooth ride, with good cornering. Noisey, but the 160 watt stereo takes care of that. 2. It's a minivan & SUV with a cavernous interior. "Ten gallon hat" headroom and expansive leg room front AND rear. Both front seats fold flat creating a double bed (don't tell your teenager), OR fold the rear seats creating a minivan cargo space. 3. Toyota reliability and smart simplification. 4. It gets 30mgh city and 34mpg highway, its True Cost to Own is among the lowest in the world. 5. Dual airbag, ABS, stability control, brake assist, and great visibility.
BMW-handling, nerdy styling, comfort, and economy. Even if it were sleek and beautiful, we would still love it (but not quite as much).
For what it is, this is pure perfection of design intelligence and build quality. I would not suggest even the slightest change. Some have experienced high incidences of cracked windshields (we have not) so maybe rigidizing the framework or ruggedizing the glass itself?
