I recently turned my car in after a 3 year lease. I had planned to get another BMW 5 series, but rising gas prices have encouraged me to consider a hybrid. In addition, if I purchase a hybrid and put it into service before the end of 2005 there is a $2000 tax advantage. (Waiting until 2006 cause the tax credit to go down to $500). I test drove a Lexus RX400h. I liked it fine, but am a little nervous about the hybrid. Does anyone have a hybrid or know someone who is driving one? Is the gas mileage really as good as they advertise?
