No probs 😀
Back to the IS-F / GS-F...... I recall the first time I drove a GS-F. I owned an IS-F at the time. I wasn't at all blown away by the GS-F. Yes, it's a much nicer place to sit, but I wouldn't say the driving experience is a world apart.
I guess you'd have to drive them back to back, but if it were me, I'd save my pennies and go with a nice example of an IS-F (in white or grey) 👍
