General comment: Wide body aerodynamic design makes even the smallest of engines fun to drive. The Spire GT-R has a long wheel base design which provides forgiving and controllable cornering for novice or experienced driver alike. Its low weight and good distribution results in exceptional acceleration, braking and cornering. This make of car is superb value for money for anyone wishing a track or road car of this type.
