My car sits higher on passenger side than drivers side

Several inches is quite a bit. What method are you using to measure? Are the tires all the proper size as per the placard on the driver's door area? You could definitely have a coil spring issue, but it'd be unusual to be that far off. Any physical damage in the history of the vehicle? A technician near you can utilize workshop manual specifications to perform an accurate measurement and inspection, and let you know the results. www.repairpal.com/repair-shops
