Hello Iam new to this site and have a question. I have a 94 chevy suburban that I have owned for some time. I purchased it from a police department , it was a police used vehicle. My question is does the suburbans used for police duty differ in any way like the caprice as far as engine or suspention? Mine still has some of the police eqiupment still on it. Iam going to change the bench front seat to buckets soon. thanks for any help.
