Chassis strength

[Lesliehedley]

When I jack up one front corner of my 400SE, the doors still open but they catch on the sills. The chassis is obviously flexing. I know wedge chassis are not particularly rigid, but would you expect the doors to catch when one corner is lifted, or is this a sign my chassis is rotten somewhere and has more flex than it should?

Ok, thanks for the feedback chaps. That's reassuring. There must be a fairly straightforward way to reduce the flex, at least a bit, if it's that bad? What about engine bay cross braces or something similar?
