I know it's a different car but its the same front engine rwd platform. When I first got my zed I was pretty bored by the handling, I'd come from a sorted Capri that I'd owned for years, so I knew how to drive it. The zed felt well as you desribe really, not very exciting. Then two things happened, firstly I realised I could go wayyyyyyy faster round corners and I then had my alignment sorted and replaced some worn crap. I quickly realised at this point it was very planted and I could go even faster.
Moral of the story is get it checked out then try harder. Front wheel drives are a lot easier to drive fast at first, but once you learn to drive a rwd car properly you will kill things. Robert who lives in Hampshire, his z32 which the rolling stock is pretty stock just prolly bushed etc, that car is faster round a track even in the wet that a 911 turbo. Get it checked out mate.
