The Corsa is built as a cheap motoring tool, you can add whatever bits you want to it but unless you replace all the trim, a lot of the suspension geometry and so on you are not going to get away from the compromises that had to be made to the setup in order to make it an effective and cheap car.
VXR can add more power, a diff if it has one, and upgrade suspension setup ... but it's not going to take away any of the compromises and cheap parts.
Something like the Astra is a larger car, so has to have fewer setup compromises anyway.
As I said, I don't mind the Astra VXR, but the only hot hatches I like are the more crazy things.
(To be fair, I'd prefer if it was crazy stuff like the current STI, the old group B stuff, the Celica [still a hatch] and so on)
Buying a Corsa for 14k is like buying a Mugen Civic for 45k, there are MUCH better cars you can get for that money
You know what would make the Corsa VXR cool though?
Make it AWD/RWD, full double wishbones at both ends, lower seating position, lose the back seats
Oh wait, it's not a proper sports car, my bad.
You're kind of contradicting yourself there. Its a 'cheap' compromise but at an overpriced 14K? Also do your research - the whole set up was designed in a wind tunnel (make of that what you will) and has been uprated...we're not just talking bodykits and suspension.
