I would have to agree with Shambles on the 'too-busy-changing-gears-to-enjoy-the-drive' syndrome (c).
My 'other' car has a six speed gearbox, and with the turbo diesel, I'm glad it's automated.
Hi CRM114 ...
I think it depends a bit on the ratios.. My wife's Nissan Tiida has 6 speeds but they are too close together. Think 6 speed i30 would be good if the 6th gear was a true overdrive. the 1.6 CRDi could pull a sixth gear with 100km spinning at 2000RPM would make for a very quiet and economical cruise...I.M.O. anyway
I agree with you here Dazz. For city driving the 5th gear in my petrol i30 is great for the 80-90km/h zones but for when I've gone on trips to Newcastle and Wollongong I find myself searching for an extra gear just to drop the revs down a bit whilst cruising at 110-115kms.
It might affect the use of the cruise control though for a manual car as it might involve changing back to 5th for some of the hills.
