Hey Chaoul, Just another friendly word of caution before putting down any money on this purchase. Make sure to get the straight story on the where, when and how the title can be obtained. There is not much more disappointing than owning a car that you can’t get the title sorted out on - Don’t Ask.
Get all the facts on the mechanical condition of the car and be sure to take the time (make the time) to have a knowledgeable 928 Porsche tech go over the vehicle. There ARE a few sweet deals out there and you may have very well found one. But just about every 928 owner has a “sadder but wiser” story about their first purchase.
Best of Luck, Michael
