100k miles ago I was not driving a Prius... So 100k miles ago I wish I knew that the Prius was as roomy, full of features, and fun to drive so I would have made the switch sooner.
I wish I knew that I wouldn't have any major problems with my Prius. I could have saved the money I spent on the extended warranty. - Ed
With a 162,000 miles of Prius experience now, my advice is: JUST DRIVE IT !! After 8 years, that's still a surprisingly effective approach. .
