Yup!

In the last 3 years this has been my experience. I bought my first Insight - a 2001 with 40K on it - drove it a year and 15K miles and sold it for $1,500 more than I had paid. Bought a 2004 Insight slightly used, drove for 20+K miles and sold it for $500 more than I had paid. I have a 2005 Prius and my wife has a 2005 Prius - we could probably sell them for what we paid right now.

Regular maintenance and fuel have been my only cost of ownership for the last 3 years!
