We've seen an E92 M3 run all over a 911S. The outcome was not surprising, but the total demolition was inexplicable based on specs. Regardless, overall, they can be informative, especially if we see different same model cars demonstrating similar performance.

Absolutely, there are really a lot of variables to keep track of. But how well are these really kept track of by any other tests? Car magazine, personal timeslips, etc. Part of the problem is that in many cases the car being compared are close enough that it becomes a drivers race instead of a vehicle test. Again all that being said, I would bet that normal everyday street encounters with stock vehicles would reflect very similar results to those of m5board.com
