Two of the finest sports coupes meet for battle, this time in Fifth Gear! Actually we can’t it’s quite rare to see a comparison test with the BMW M3 GTS, because it is a very rare special edition. But here it’s in the capable hands of Vicki Butler-Henderson and she goes head to head with Tiff Needell in the Porsche 911 GT3 RS. Both cars have scaffolding (roll cage) at the back which make them look a bit stupid to be honest, but as far performance matters, they’re both superb. See which one is best in the video after the jump.
