I think we can do better than the 2002 guys 
1. By reading this you are now knee deep in poop.
2. If you replace the VR, you need to "dress" or smooth out the brass slip ring inside the alternator. If you do not, the slip ring will chew up the carbon contacts of the VR. Also the new VR may not work properly.
3. Adding to what JR aka Jackson said, get a copy of the 924S/944 parts interchange list.
4. If no one has replied to your call for help or post, you can use the "
Search" key.
5. The fuel tank has a fuel strainer that keep chunks of dirt & sludge out of your expensive fuel pump
6. Do you notice the coolant reservoir goes down a little every couple of months? Get a coolant pressure tester to check for pin leaks-----or replace your head gasket.
7. When you sell the car, list all the mods you added and the maintenance done---then change your telephone number and move. The green/new owner will stalk you.
8. Members with join dates before 2000 are the "cool" senior members. The era of the Pelican BB bulletin board.
9. If you buy a very low mileage car, it may cost you more in repairs. The cars need to be driven as mentioned. The seals. gaskets, shocks, belts, rollers, and a ton of other stuff will need to be replaced. Buy from someone who has already put $10K in the car and you can buy it for $5k. It may not have fresh paint or the interior smell of a new car but it will be cheaper.
10. Will the 944s become collectables?
Only by the pleasure it brings the owner.
