I would love to help but wife is at work and I have the kids.
However if you live in Fife then Dial-a-tow recover local for £30.
Dial-a-Tow pm me if you need the number but it's on their web page.
I have used them before and they are fairly trustworthy.
Depends on your personal prefrance have had both and prefer the auto.
There is no loss of control as you can lock the box in 1,2,3 if needed on a disco 1.
I would say test drive both and go with the one you prefer.
Love Ducati had a 999 but got bored so that's when I got the Fireblade. I'm 6'3" and I don't find it to small. Will probably go back to Ducati when I'm done with it.
Had an R1 found it to small for me got a fireblade now couldn't be happier.
as for your disco wait untill the white stuff comes in a few months and you may get about £2000 to the right buyer
