They are all three the same basic vehicle. BASIC vehicle. The differences are always noticable. Just as a small example all the amenities, (such as carpeting, cigarette lighters, courtesy lights, radio, electric seats), are of a hight quality in the Cadillac. Shocks are a better quality. But the basic frame & 'shell' of the vehicles are the same. Is it worth the $$ difference. It all depends on the person purchasing the vehicle. Some people buy a vehicle for transportation and look for economy. They buy the Chevy. Some people purcahse a vehicle for transportation, emotion, luxury. They buy the Caddy. All I can tell you is: Once you own a Caddy, you'll never want anything else.
