That said, they are incredible cars once wound to speed with great handling but getting them to speed will feel slow compared to a 986 especially an NA unit. They have delicate gearboxes as well.

What is the typical frequency and expense of changing the valve train belts....

I was doing them at 15K and this was in the nineties and the cost was 7-800 range, I think the service interval was 20K or 25K. With a 944 you are always revving it hard, hence the doing it early, the oil seal should be changed each time as well. There is a special tension tool for setting the belts and because the engine uses a counter balancer it is a somewhat complicated arrangement. Clutch jobs were expensive, lots of dis assembly, around two grand at a good indy back then. I'd say keeping the car from overheating would be the largest challenge. Also, if it's important to have ice cold free flowing AC you do not want a 944. The system is weak and robs huge engine power, the rear glass is like a greenhouse too so the interior can get pretty hot, couldn't see it in say Arizona.
