You shouldn't need to double declutch. It could be the gearbox oil or the bushes on the gear lever mechanism. On mine I found the librands manifold released mid range torque
A pause is all that is required really. Just not to rush it. I think it improves a fraction once warm. I haven't changed the gearbox oil yet. Changed the diff' oil, which came out very clean.
Nice looking car. The back seat looks very "deluxe"...I haven't seen one like that before.

I think it is all standard. Just the bench type cushions with a bit of fluting to give shape. Lap belts only in rear of course.
I think it may have had front head restraints (1996) but they didn't come with the car, just the plastic blanks.
