I drive a quad plate and although it's not a daily driver, I don't see why it can't be driven daily if need to. I've driven it to work and back a couple of times including after office traffic jams and stuff (Klang to UMMC) without breaking a sweat.
It's an OS Giken quad plate which is as light as OEM I might say. Had an HKS twin plate which was a bitch to drive in traffic jams though others may be okay with it.
So it depends on the brand/type of clutch as well as how u drive.
It is relatively cheap to daily drive a performance car (cheap means bearable, though u obviously can't compare it to a Myvi laa..). And like what V-Spec has mentioned, it gets expensive if u start to mod it.
Erm.. Why would u have a twin plate clutch? Buying a modded car I suppose? Be prepared to spend some for wear & tear mantenance.. Which may be just the regular fluid changes (engine, differential, gearbox oils, radiator fluids etc) or could include more expensive things like tyres, brake pads, engine overhaul etc).
I'd suggest those who intend to buy these cars to get a stock standard car if possible as maintenance cost would be fairly minimal and u don't get the bug to mod that quickly (maybe).
Good luck in ur search and hope u enjoy ur ownership of the Skyline. Join us on drives.. Which is almost weekly thanks to the cravings of our
