My company is getting rid of the owner's car - a 2006 Lexus RX400h. The car is in very good condition and has been maintained by the dealership over the years.

I'm thinking of giving this to my 87 year old mom as her car is starting to fall apart. I'm wondering about the hybrid battery. Is this something that I personally can replace or is this a specialty job. And, does anyone know the approximate cost of this job. I looked on the internet and I see batteries for sale ranging from $1200 to $2000 but on another site there are estimates for replacing the battery at 6-7k, quite a big difference.

The car is going to be free to me, and it has about 150k miles on it. The owners live on the east coast and this is CA so the car has basically been used every 6 weeks for highway transportation its entire life.

Any thoughts?
