I can confirm that if you order your new car with a bonnet strap, the two centre louvers are not pressed into the bonnet. I think this configuration looks like a finished custom build, avoids the potential rubbing on raised metal and keeps the strap fitting snugly to minimise the collection of dirt.
At this point I must declare I am a big fan of a bonnet strap on the classic. I think they are appropriate and add that vintage touch to the car. My 2011 4/4 has covered just over 5K with the factory fitted strap. There is no sign of marks or scratching BUT, I do keep the wool backing clean. These means checking the wool every time I wash the car and using a nail brush with soapy water to clean what dust and road grime does accumulate.
