Is it possible to have a classic sports car as a daily driver?
 

If your going with a replica that has a modern or updated powertrain then you will be fine. I also suggest having a back up car because the classic sports cars were not well insulated, against noise and it will be a big change from a porsche piwis 2 new car. I have a 1979 Lamborghini Countach and I drive it maybe once or twice a week as its not very convinent ,I.E : No cup holders, very loud, rough ride horrible mileage, touchy carburetors, hard to find replacement parts, For instance I can't go to Autozone and get a set of Brake pads. I would say get a classic to enjoy one or two days a week and something newer to enjoy the rest of the time.
