Whats up every body, im currently looking for an 04 rx8, and some of the 8 i came across had 90 to 00k miles on it. Is it a good idea to buy one or stay away from it completely.

As RIWWP said, reading the thread he posted is a must when looking for an 8. They are just different enough from regular cars that the knowledge contained in that thread is worth its weight in gold.
As far as the mileage is concerned, I would keep looking to see if there is anything else available as buying a high-mileage 8 as a first rotary car should be a last resort, IMHO. The lower the mileage, the better it will be for you in the long run as higher mileage cars, as a whole, will require more parts replacement sooner, particularly if you have no maintenance history for the car.
Don't jump at the first 8 that rears its head. Be patient and the right car for you and your budget will come along.
