When I had my '08 V10 I did the plugs myself in 90 minutes. I was in no hurry and took my time, if i had to do it again I could do it in a hour. It's an easy engine to work on. I also had a 2000 V10 and the '08 had a lot more power and would easily outrun the '00. So I would highly recommend the '05-'10 V10's and if you can get one with 4:30 gears. It will bring a smile to your face.
