Hey ssflai,
As you can see, I am pretty new to the forum but I wish I had discovered this forum before my purchase last year. I knew the standard procedures from past car buying experience and did drive many Boxsters before I made my purchase. I did do a PPI and carfax history before my purchase.
There are so many threads in this forum that is helpful. NickCats has a thread in the general forum that has three links for Mike Fock and RandallNeighbor..... very, very helpful. Also, the long thread regarding Sloan's search for a Boxster was helpful as well.
Have fun and enjoy your purchase.... Spring is coming
