GTP's and tall drivers

[Dash6]

Hi all, looking for some feedback from taller drivers of manual GTP's, B series in particular.
I've got my GTP up for sale at the moment and have had 2 potential buyers (both approx 6'2 as claimed by one) and have both struggled with the clearance between the steering wheel and the left leg when operating the clutch.
Personally its not an issue for me as I'm short with short legs.
The issue the potential buyers had were they felt the front of the seat sat to high and couldn't drop it any lower using the seat controls on the side.
Do any taller manual GTP drivers out there have this same issue or methods to drop the seat height?

Cheers
