Correct, front bumper is bolt on for the years listed. Front also I think is the same as was used on the Boxster S, as those had the 3rd radiator. Rear is 911 only, and I "think" 99-04. The refurb bumper places sell them in the $90 to $200 range, whereas people selling due to upgrades and the like range from $175 to $500 from what I have seen. The aftermarket replacement types (that look nothing like stock) tend to run $500 to $1500. Shipping can vary a lot though, and is usually the deal breaker both for the hassle on the sellers end, and cost on the buyers.
I need front and rear for my boxster, and have been researching.
Some of the aftermarket ones are just silly, but the stock one is a little plain for my aero kit rockers.
I had a coworker friend up in Charlotte yesterday too, go figure.
