I agree with you but personally looks aside I perfer the 350z looks no because the other one is "hairdresser" i just perfer it.
The boxster is a better car though IMO but you pay for it. interior is basic but good quality, leather covered dash. its spars but serves it purpose. Also the boxster is a convertable so thats +1. the engine is argubly in a better place. Everything on the boxster is typically German over enginereed. Great cars IMO. If you the best driving experiance the boxster wins hands down.
