I've owned a mk2 16v, mk3 VR6, passat GT 16v, Audi 100 quattro and now Audi A8.
I've also had regular use of a mk3 16v and an Audi 90 Quattro 20v( I think i've remembered everything

)
I find some of the times quoted on the mk2 16v interesting, it was a quick car, but not that quick. I don't think it was any quicker than the mk3 16v.
If a 16v could do 0-60 in close to 7 seconds, then that on paper, is nearly as quick as my A8, and that frankly is laughable.
Just to add the mk3 VR6 was a fair bit quicker than the mk2 16v, its a shame the handling didn't match.
Oh course this is only based on my own experiences of the last 15 years.
