Hyundai Coupe seats in my old Sprinty
As Reuben says, they are very comfortable. Fitting wasn't easy, as the hole centres on the Hyundai seats are wider than the Coupe as well as longer front to rear. Also bizarrely, the Coupe's "tunnel" isn't actually in the centre of the car, meaning one seat needed to be spaced further out than the other. The diagram below is for the passenger's seat - the driver's seat had to be moved to the right)
I ended up making the plates with multiple mounting holes so that I could alter the position of the seat side-to-side
