Crooked car

My plus 2 when viewed from front or rear has a gentle slope to drivers side,iv measured this to be maybe one inch max lower.Car handles lovely,drives straight…so should i put this down to the years or try to rectify?

Do you mean it’s lower on the driver’s side?

If so, does/did the car get much mileage with only the driver in it?

If so, may benefit from new springs?

Stuart.
