Why would you think that?

The Beemer 7 series is a tank ! only the 735 or 745 would be a challenge !
Usually driven by rich c.nts who own companies or their personal driver - so
none would do more than 70 anyway!
XK8 are driven by old fudders who never go over 82mph, and watch that back
end slip on tight motorway curves :)
A porche maybe a little tougher to contend with but like you siad - the 147
3.7 GTA would have a good pop at it...

I find many drivers shift back into the middle lane with the new sporty 156
face in thier rear view mirror and a quick flash of the fogs !! The only car
I have a ball ache with are the Astra Diesel Vans ! For some reason they
just seem to have en-equalled turbo power...
