The GTS (also known as Sport GTS or even Sport GT-S) is the top-of-tree most sporty of the QP range. It has the sports seats, fixed rate lowered sports suspension, bigger brakes, grey 20 inch wheels with a tyre size specific to the GTS, alcantara seat facings and roof lining, carbon fibre dash and door inserts, shadow chrome window surrounds and exhaust tips, body matching door handles, and a few other bits and bobs.
The Sport GT is the model one rung below. Still has the 20 inch wheels, but not the other above listed elements and is less sporty to drive. Very nice though, and a little cheaper.
My QP Sport-GTS is for sale for not too much over £20k. It's my 4th QP and by far the best of the lot. Advertised on Pistonheads at £23,750 but I'm happy to negotiate on that as I have already bought it's replacement so need to move it on.
Many on here know the car - it's the blue one!
