Oldtimer or rather something newer ?!

Hi guys, I haven’t been able to decide between this thing for a while.. Should it be rather a classic car? Because I just like it better. Or rather something newer? Because it is more reliable and does not bring such high costs. My taste : In terms of vintage cars I like cars like : Pontiac Bonneville ; Catalina Ford Thunderbild ; Mustang (older models ́65 rumm) Mercedes (the series with the vertical headlights) In terms of ,,,newer cars ́ ́ f all me : Mercedes SLK R171 ; C-Class Mazda RX 8 Subaru Impreza WRX (Coupe) Mitsubishi Lancer X My budget is about 13000,00€ Since I as a trainee should earn about 900€ per month the car of course not have a 7L engine .. What is always a very difficult topic with a Pontiac and with Ford .. Besides, I would like to make short trips again and again (Italy etc.) I am not forced to drive fast even if this seems like this with the newer models (Lancer ; Impreza) but it makes me of course a lot of fun. If you know other cars that look so similar then I would be very happy if you would call me this !! Greetings Mario
