I figure I would just throw this out there. I think it is a long shot but here goes.
I have the Grey color leather comfort seats in my 2005 Vintage Speedster and would be interested in trading to the vented sport bucket style seats.
The car has 5000 miles on it and the seats still look like "near new" condition. Nothing wrong with them. I had swapped the bottom cushions, Left for right, when I purchased the car last year to help in having the cushions wear evenly. It possible the previous owner may had done the same since the wear on the cushions are no different from each other.
I am interested in replacing with the vented sport bucket style in grey leather to match my interior.
If someone has a set for sale, I may be interested in a purchase and then sell off my existing ones.
