Shorty - Craggy has the Cliosport credentials, you just need to have been around a little longer to realise why. His Willy is undergoing major restoration work so he runs around in a VTS until the insurance runs out.
IMHO - the VTS is fairly quick but I wouldnt say in the same league as a 172, its basically a short geared sprint car, as a lot of hot hatches are these days, 0-60 is what people want, so it doesnt matter if it cant do 130 on the motorway, as long as it cracks 0-60 in 7-8 seconds.
Personally I dont believe a standard VTS or 106GTi can do a genuine 130 anything, let alone 140+
At these sort of speeds all you need is half decent aerodynamics and POWER. Doesnt matter how quick you can get to 60 through low final drive/gearing or light weight, if you havent got the outright power then you wont run a decent top speed. Theres certainly an argument for saying who cares if you cant do 130-140, as long as youre quick over the sprints. Who honestly does that sort of speed anyway? I cruise at around 100-120 on the motorway, on a clear road, any more just costs huge amounts in fuel and is tricky if theres anyone else on the road.
Not that Im saying that I love Saxos. But VTS and 106GTi are quite quick, not as quick as a 172, but not as slow as some people think. Most VTS/GTi owners do seem to think they drive rocket ships though!
