Craig, I've got two SVT's so I likely have more than anyone this side of Montreal. Actually, one might say I've got 1.5 as I wrote the 98 off in Septmeber.
Regarding reading the MPH/KPH, my vision isn't great for detail anymore

so it's difficult to see the small inner KPH readings and I tend to drive much faster than I should

, especially in the SVT

.
It's most important for pulling my speed down and quickly seeing where I need to get it to when I spot a ghost car, etc

.
Regards, Alan
