I don't know about others, but driving down the road in 1/4 mile sections to get somewhere isn't how I judge a car's performance, nor is it how I drive to get from point A to point B. I have a friend that owns a Viper, one of the first... it's fast, it's dangerous ...

... but ...

Can it take going 135 MPH for long periods of time? I had a 1966 MGB, it was a dog off the line, but on the road it handled every curve the engineers could throw at it and it ran and ran and ran and ... well ... ran at high speeds for long periods of time.

To me, a cars performance should be rated on the long run. The 1/4 mile segments ... those are just peeing contests - IMO.

I think my XF takes the long runs better than my friends Viper ... and when people see his Viper they know what it is ... when the see my XF ... I get asked what it is.
