i would go the rotor, only cause when i had my CA it was a ongoing money pit, yeah i know rotories dont have good reputations but i think people who say that never drove one.. i have been around rotories for a while and the reason i went for a rotor instead of CA is i dont want full power or the quickest car on the street i wanted a cruiser for weekends that sounded like sex on wheels and i can tell you chicks love it and if the day comes i want power i can assure you no CA will ever catch a decent 13b, you tell me who has ever seen a CA with over 1000hp? ive seen rotories at that figure.... and i know a 20B rotor would fit in a datsun and put out over 500kw on standard n/a..

but its what you want to do with it...
