When I was shopping for a sports car I drove a C6 6 speed, loved the car was low miles but couldn't agree on a price. Then I found my 2000S, love the car its quick really fun to drive perfect for my needs and was half the cost.
Honestly I was more comfortable in the vette, handled nice, V8 tone ect...
But The Boxster just drives like as mentioned a go cart where as the vette feels like a bruiser the Boxster felt more sophisticated.
In my opinion they are apple and oranges both fun but in different ways. My wife still wants a vette just for the look. I would love a C8 lol
Best thing to do is drive em both decide what you like best buy it and the enjoy it!
