so just started driving and my parents let me have our old family car, its a 92 civic but its the 4 door version. its reliable and everything and runs fine but i want to eventually go for more performance and fun

so i guess my question is: is it worth it to engine swap/all that stuff on my current car to get performance boosts, or sell it and buy another car? if i do sell it how much do you think i'd get it for? its pretty clean but has minor cosmetic problems on top of the left wheel but other than that no dents etc and engine is still strong
also if buying another car i'm looking for another civic but hatchback or crx, what year/version should i look for? obviously within the price range that i can sell this civic for, maybe + a few hundred or so
shitload of questions but thanks
