The problem with "hot hatches" now is that since the saxo/106 theres been a new level of hatches on the market like the astra vxr, r26, focus st/rs etc. Hot hatches used to be 100bhp, now its 200+. IMO a hot hatch is simply a hatchback that you can use for every day but still have loads of fun in it chucking it around a tight b road. In the same way we had supercars, and now have hyper cars, hot hatches have divided into two categories. The c2 vts is a fun little car to chuck around, and if mine hadn't of just been written off, i would have kept it for quite a while more.
To the OP, one very important thing to check before buying the car is the inlet manifold bolts/studs. Its a known problem with the VTS, and WILL happen eventually. Push down on the inlet and if it starts to whistle it means they are loose, you might even hear it on idle without pushing down. Its an expensive fix if done at a dealer, although it is covered by warranty. They will refuse to fix it for free out of warranty, although its a known problem at HQ with every VTS.
