Opel Speedster

Hello together, to the speedster drivers, have an interest in a speedster, what do you recommend? Above all, who drives one here and can give me some information about the car? I think the 2.2 suction cup version would be enough for me, is the car suitable for everyday use, i.e. also to drive with the hardtop in winter? What has to be taken into account when buying? If you don’t want to invest more than 20,000, you can get something reasonable for this? what equipment should the car have? Which year? Thank you in advance!
