Opel Calibra performance??

Hello! I’m new here and I want to start with a question about Calibra. For a long time I have been playing with the idea to buy a Calibra as a “summer vehicle” … since I don’t intend to drive the car forever I would be interested in the anticipated price development. In my sights I would have a Calibra 2.0 8V 116PS in smoke grey from 1994. Run it is 104,000km and is equipped with sliding roof, central locking, el. window lifters, on-board computer and light metal rims t. It is – except for a sports exhaust – in original condition. According to the description it has hardly rust and was moved very rarely in winter. The good piece should cost € 2.980,-. Presumably I will drive it about 2 summers and then sell it again. Can I expect that I will still get about the same in 2 years? Thanks in advance for your words!
