I chose my Acura for one simple reason... it fit what I desired in my price range.
I am not an "import" only guy... hell, I have owned all the major brands at one time or another...
When I was looking at cars, the integra was the best thing for under $25K with the most support. The vehicle was small and semi light. It was very nimble. It was pepy. It was fun to drive and it offered all the luxury I desired.
If big american cars are what is desired... then own one. If smaller imports are desired, then own one...
I have nothing against either, I say just choose a car that fits you. Just make sure it can keep up with the rest of 'em...
