I added up my option code a while back, and found out that my 1999 Ocean Blue Boxster was originally about $53k + dealer markup, tax, and licensing. So it was probably closer to about $56-60k new. (If you want to see the option code it is on my website in my signature.)
I paid less than half of that and the car only had 17k miles! Although I have added about $2500 in factory features to the car since getting it (hardtop, RTS, rear speakers, etc.)
