323 F – A good used man?

Hello, I would like to buy a sporty Japanese coupe in February or March of the next year. For max. 2000-3000 €. I had actually fixed a Civic coupe ej2. If not my cousin from Austria would have come to visit. He has a 88 HP 323 F and I have to say the car is cool. Unfortunately, the 323 c is all the more ugly (my opinion) that I have to take a 5 doorr if I choose a 323 f. My questions are: How robust is the car(rust, processing) g)? What mileage is to be trusted with the engines? How cheap are they in maintenance (insurance of dad 30% )? Which engine is receptive? Are there specific diseases? I am grateful for any help MfG
