I am intrigued that an automatic should require a new clutch. As far as I know, the only clutches in automatics are internal to the gearbox and, unlike manual gearbox clutches, there is no way a driver can abuse them and cause premature wear. With manuals some drivers ride the clutch and hold the car in traffic, causing extra wear, which is the reason they are excluded from most warranties. Wear on an automatics clutches can only be caused by gearbox, not driver, problems so should not be excluded from warranties. I've been driving automatics for many years now, at least three have done 150,000 miles plus, and none have had clutch problems. A good reason for buying automatics second-hand is that driver abuse of both the engine and gearbox is not possible since the electronics prevent engine over-revving and over loading.
