In my experience a decent front wheel drive car is fun.. Eg 306 gti6, 205 gti, clio 172 cup and even an accord type-r (probably integra and ctr, never driven though)
All of these can easily be tail happy if provoked (in the 205's case all the time!)
Whereas a poorly set up fwd car is painful to drive fast like a mk4 golf and a LCR in standard form. Focus ST for me fall somewhere between the two not terrible, but not up there with the best.
Can't comment on how other RWD cars compare against the Zed though as its all I've driven.
