You can buy better for the money. Drove the GF's for a couple of weeks in the summer. Brakes were good, but the car just felt so sloppy. Specifically, the ride is what did it for me, it crashes and then wobbles over bumps. This was also a Mk 1.5 (97 on). I'm not comparing it to a supercar either, just to my 306 which has done over 100k miles.
One possible good point for new drivers, is that the car gives you lots of warning when you are losing grip with progressive understeer if you are pushing it too hard. Unlike my peugeot which will grip and grip until it runs out and starts under or oversteering quite dramatically...
If you have to have a corsa, ignore the 1.2 8v and the 1.7D, these are the worst of the bunch, even for a learner driver, i would not recommend these as they are almost dangerously underpowered.
If you are a younger driver in a high risk area (i.e: Northen Ireland or London), those 1.0 12v's are damn cheap to run and insure though.
