Pros: Great gas mileage, comfortable, lots of room
Cons: Took long time to get fixed after accident
We purchased our Prius in May of 2007 and we have been very happy with it. It gets great gas mileage and it's very comfortable and roomy. The only downside we have encountered is that after hitting a large deer, the car was out of commission for 6 weeks (which at the time was longer than we had actually owned the car). Apparently it took a long time to get replacement parts.
Aside from the long wait time, we have not had any other issues.
We feel that we've made a good decision and have hopefully encouraged others to do the same.
