Oh well 'wormole' we can have our opinions that's why we live in this society, (Mods excluded of course).
I don't believe it was quality that let the earlier jags down they had it everwhere, strong bodies, wood & leather everywhere built like tanks it was reliability via some pretty poor designs that let 'em down. You can have a terrific 'quality' item but with a poor design it's going to give problems regardless of it's quality, this is what the earlier Jags had I believe. I know to some degree this to be true 'cause I cut my teeth on during my apprenticeship on a lot of pommy stuff, mainly BMC & Jaguar,Leyland etc hence I owned a Jag when I 'thought' I knew best!
That was done all the while I watched planes fly over head & thought yep I wanna be rich like them guys !!!
Anyway with a restored jag it's more about looks than anything else & the Jag beats 'em all in that area, if you want reliability go buy a Jap car !
