Joseph,
First, this is a PUBLIC forum. Your phone number is now out there for the entire world to see. I recommend that people do NOT put personal information on the forum.
Second, there are two ways for you to reach out to Sead and contact him. If the sale of the car is first offer first sale, than why wait for him to find this message and contact you? Private message within the forum, or direct email between the two of you. Please see attached.
