@Killysprint I am just over 3 months in to ownership with my Gsf and the car just gets better and better for me, nothing gone wrong, no surprises there, and no niggles or things I don't like about it, quite the opposite.
The size of the car for me isn't an issue, I did think it would be, I parked my Isf next to it when I picked it up and as you say there is quite a difference, however on the road its a different story, when "making progress" the size seems to disappear and it really does feel quite different to the Isf.
One thing you will really need to get used to, the amount of attention the car gets, it has really surprised me.
I know what you are saying about the depreciation it is incredible in the first 2 years and while I do think about where the value of the car will be in 3-4 years it did not influence my decision and never has done really, once I have made my decision on a car then that's it I am having it.
Keep us posted..........
