This 1984 Porsche 944 sounds like a fantastic find! With only two owners, low mileage, and original paint, it retains its authenticity and likely has been well cared for over the years. The inclusion of a sunroof, good heating and air conditioning , and a functioning radio add to its appeal and comfort.
At an asking price of $9000 or best offer, it seems like a reasonable deal for such well maintained classics sport car. However, as always, it's wise to have a through inspection done to ensure everything is in good working order before finalizing any purchase.
If everything checks out, this 944 could be a great investment and  joy to drive for  to come!
