That's low hours for sure but no issues still probably means you will spend lots (tons) of money on it. I see different estimates on the supercharger rebuild from 100 to 200 hours in my research...
A non supercharger model would be more practical as it should get better gas mileage and maybe less problems depending on how well it is maintained.
Personally, I think $5,900 is too much for a 2004 but you will have to decide that.
