Not sure if that's still the case but in the early nineties it was common practise at the Dutch Volvo production facility that the quality control department selected, on an at random basis, cars directly from the production line for an extensive testdrive on a predetermined course through the local country side in Limburg (extensive as in a 60 minutes drive)
To cover 40 miles in 1 hour shouldn't be too difficult
Suppose you can always check with the production facility for clarification if you've fallen in love with that particular car.
