paul,

read the post again. SALE price was 11k although retail price is 14k+.

check carlsen porsche web site. now they have it for 12k.

you can read the tbs from porsche at renntech and check out what porsche states as installation time for x51.

with an out of state order for the x51 parts you will save taxes on the 11k-12k.
