2012 Toyota Sienna Minivan LE 8-Passenger 4dr Minivan (3.5L 6cyl 6A)
very preliminary report
 This report is after just 800+ miles, four tanks of gas, and one hand washing. The van is very quiet and comfortable. The powertrain, especially the transmission, is very smooth. Steering is silky smooth also. I'm happy with the purchase. Although you can't see any of the four corners of the van from the drivers seat, it does feel a lot more responsive and tossable than the 2004 we have.
