Its top speed is listed as 170 mph. Lateral Gs are reported in excess of 1.2. Noble enthusiasts often modify their cars for even greater performance. It is widely believed that just 165 M12 GTO 3-R models were made in the UK upon the owners findings on such sites as pistonheads.com and even fewer were made for the GTO-3 and GTO versions.
