I still believe the co 2 levels for both is a factor, none as we know come under the magic 225cgm, that combined with the big hit on residuals for someone to buy it privately just doesn't help buyer confidence. Business users have their problems.
ive been fortunate enough to buy these types of cars in the past new, I won't do it any more partly for these reasons it just not sound economics, as someone mentioned recently the IS-F is a lot of car for 20-30k, is the G & R worth the extra spend.
It obviously depends on you own personal financial circumstances
I would have either the G or R in a heart beat when they come down to the price levels of the F, I've not driven either but have read a great deal I'm personally impressed.
