What do check for if getting a porsche 944?

Im planning on getting a 87 porsche 944 and its km is 50000 which is extreamly low but hes asking 8500 for it so im trying to press him down a bit on the price so i need some advice on what these porsche have that needs to be replaced every or maybe something that breaks fast so i could see if its broken so i could get it for a bit cheaper

Please leave an answer if you had one or know much about cars :)
Thank you

An absolute must: Have the car looked at mechanically by a qualified, specialized Porsche mechanic, not the type that repairs Hondas, Volvos, and M-Benz. You want a mechanic that knows these cars inside and out. It might cost you a couple hundred, but if you're serious about this car, it'll be the wisest investment you make.
