Porsche Boxster? Any opinions? Power good? What would you compare it's power to, a 3 series BMW??

l drove one. l drove all BMW 3 series & the Boxster.
It does not need power.
It is very quick. It is an aerodynamic & light car. And it handles very well too.

The BMW 3 series has similar power. Both have 6 cylinder engines. The Boxster has about 15 more HP.
But the BMW is much slower. It is not a sports car. It is a sporty sedan. It is heavier. It does not handles as well. It is not aerodynamic like Porsche's.

If it was the BMW M3, which is more expensive than the Porsche Boxster S, then it would be the same in performance.

The BMW 3 series does not even compare to the Boxster in performance. The Boxster is at another level.
