I have known clutches to be so light or so heavy that it is difficult to find the biting point but all the manual cars I have driven have had one - do you know the make/model of clutch?
I have known cars with clutches like that - you have to be very aware of resting your foot on the clutch whilst driving as it will obviously disengage really easily.
i had a jeep cherokee that had a biting point that was near to completely released. I got very used to it...bit of a shock when i bought the Rav4 which is much more civilised. I bunnyhopped all the way down the side road when i started driving it!
Sounds like its more suitable for racing/rallying where you bang the clutch in and out and change it every five minutes than normal everyday traffic congetion type driving - if it is for an everyday motor I'd avoid it if I were you.
only about 300 yards, The garage is on a service road, you go down it about 500 yards onto a roundabout that is part of the dual carriageway. I did it a couple of times on the test drive, the nice bloke from the garage who came with me thought it was hilarious.
Why would you want to fit a stage 3 clutch to any car unless it's been seriously modified so the standard clutch can't handle the power?, On a fairly standard car you'll get no benefit (other than increasing wear on things like the thrust bearing)
