Motor vehicle side wall construction for a motor vehicle having a vehicle wall and at least one first lower side wall element which is arranged on the inside of the vehicle wall, serves to produce a side wall trim and is fastened relative to the vehicle wall, wherein a second upper side wall element is arranged directly adjacent above the first side wall element in such a way that by inserting the first side wall element into a corresponding receiving portion of the second side wall element, which receiving portion cooperates with the insertion portion of the first side wall element, a form-fit connection is produced in the transverse direction of the vehicle, wherein the receiving portion of the second side wall element is arranged in the region of a side edge on the side facing away from the vehicle interior in the final installed state and an insertion portion is formed on the receiving portion with a wall region which, in the installed state, is oriented obliquely in the vehicle vertical direction and in the vehicle transverse direction, and wherein the insertion portion has an offset directed towards the outside of the vehicle, characterized in that the receiving section of the second side wall element is formed by an inner wall section oriented towards the vehicle interior and an outer wall section arranged on the side of the inner wall section facing away from the vehicle interior, in that the outer wall section comprises a guide section extending over a first height (hF), in that the insertion section adjoins on the underside of the guide section, in that the outer wall section in the insertion section extends downwards from the guide section in the vehicle vertical direction and outwards in the vehicle transverse direction, in that the insertion section is formed by an upper wall section extending over a second height (hE), in that the second height (hE) of the insertion section is measured from an upper edge to an offset, and in that the offset is formed in that the wall section has an S-shaped curvature. wherein a second upper side wall element is arranged directly adjacent above the first side wall element in such a way that by inserting the first side wall element into a corresponding receiving portion of the second side wall element, which receiving portion cooperates with the insertion portion of the first side wall element, a form-fit connection is produced in the transverse direction of the vehicle, wherein the receiving portion of the second side wall element is arranged in the region of a side edge on the side facing away from the vehicle interior in the final installed state and an insertion portion is formed on the receiving portion with a wall region which, in the installed state, is oriented obliquely in the vehicle vertical direction and in the vehicle transverse direction, and wherein the insertion portion has an offset directed towards the outside of the vehicle, characterized in that the receiving section of the second side wall element is formed by an inner wall section oriented towards the vehicle interior and an outer wall section arranged on the side of the inner wall section facing away from the vehicle interior, in that the outer wall section comprises a guide section extending over a first height (hF), in that the insertion section adjoins on the underside of the guide section, in that the outer wall section in the insertion section extends downwards from the guide section in the vehicle vertical direction and outwards in the vehicle transverse direction, in that the insertion section is formed by an upper wall section extending over a second height (hE), in that the second height (hE) of the insertion section is measured from an upper edge to an offset, and in that the offset is formed in that the wall section has an S-shaped curvature.
