suspension question

I have a question for you guys. I really want to lower my car but i dont want to scrap over bumps and potholes. my cousin has a lowered car and he drags over eveything. I was wondering if it is possible to have a thing that can lower or jack up the car to it normal height at a push of a button but still give me performace? I drive a Toyota Celica right now.

Airbags are a viable option, but I don't know for a fact if they are suitable for a Toyota Celica.

Another ooption is hydraluics but I would not suggest that for an everyday driver. I'mn sure you can find an airbag suspensipon kit somewhere for your suspension but you might need to look for it. My current car has a self ajustable air ride suspension. When they are new, they ride liek a dream but will usually wear out fast and are quite expensive to replace, but I dont think you will have the same problems with the airbag suspension.
