i have a 92 sedan dx and for some reason the car sits about 1 inch or little lower than what the stock hieght is.. how can you tell if there are after market springs under the car? or can the springs get weak and get lower.. any help would be great

 

typically you can just tell by the finish on thet springs unless the original owner dropped it right away but if they bought a dx sedan i sorta doubt it. also is the consistanly lower because ive see corners and even sides sag but if the whole car sagged evenly that would be odd.
