I am looking at a 2004 911 4S and since I am a first time Porsche buyer I could use some help in asking the right questions. Additionally are there any problems with that year and model that I should be concerned about. Or any particular questions to ask in general to ask before buying a Porsche.

 

Look at 996 board

 

Do you plan on tracking the car?

 

My first questions would be...
Are you the first owner and do you have all the service records, keys, books, and other stuff that came with the car ? You want to hear " Yes " to both sides of that question.
In my opinion, anything short of that would never get to the next stage which is getting a PPI from a reputable Porsche service center or knowledgeable independent specialist. They'll know the answers to your second question which, unless blatantly obvious, you can not determine with a casual test drive.
If you can't find an '04 that meets the " one owner requirement - got the stuff " question keep looking at newer cars until you find one.
Lot's of info and many opinions on a site like this so do some homework on your own. These cars are great fun to own and drive if you get a good one.
