Hey scotty! I own a 2000 porsche boxster that has 79k miles on her.

Alternator belt recently replaced

Hosing system recently replaced

Coolant system recently replaced

Spark plug tubes/seals replaced

Spark plug(s) replaced

Engine oil cooler line(s) repaired/replaced

Cabin air filter replaced/cleaned

PCV valve replaced

Air filter replaced

All of the things listed above has been replaced and she has little to no rust. I am 6 feet tall and it kind of feels like a go cart to me and I do want something faster and a little bigger you could say. Should I keep her for now? Dealerships say they can take the porsche for 6k to be nice but its a porsche and I feel like it is worth more... private sale is maybe the right move but im not positive. What do you think I should do with her, maybe keep it.. not sure! If I do keep her what problems should I be aware of? Thanks!
