Here in Spain - like many I'm often looking for 6th (or is that 8th). An overdrive maybe a better idea. Better still Lock-up auto with overdrive please Mr Bloor!
But in the UK on the smaller country roads around my mum's home I often had trouble getting as high as 4th. And BOY! did consumption suffer.
So Diesel too Mr Bloor, whilst we're at it.
Oddly I've just removed my GiPro as frankly all it did was annoy me.
