Yuyp. I bought a second hand XJS that had been in a smash..and fixed.
Well I drove it for two years through to its SECOND MOT after I bought
it before they discovered that the actual kingpin was bent, and this had
been taken out with extremely offset track rods and a few other
adjustments. A fast corner on an undulating surface had it squirreling
like mad! You get the same with a lot of McPherson strut type suspension
layouts as standard.

A tale that is remarkably interesting.

Not least because an XJS does not have either kingpins or MacPherson
strut suspension.
