Rear sag

Is it normal for the stock suspension to sag in the rear after some time?

I just bought the car last week. Maybe the last owner pimped out some fat chicks.

Maybe post some pics? Or take it to the shop and check for leaking shocks or damaged springs. Check the shock mounts too as those can wear out

Just that the springs are slightly shorter.

Typically it would be the suspension bushings wearing out, and the camber starts to slide (then the back squats). But it shouldn't be a lot.

I don't think you could keep enough load in the trunk of this car to cause permanent damage to the springs though (unless you haul sod all day)
