They're Mk1 MGF seats which are the pleated leather - look quite classic. The door cards are JK. Not an exact March but close. Try MGF Centre where I got mine from.
I have Hyundai coupe seats - nice low base. I also wnet through SAAB/Vectra Elite first with no joy, I also tried Mazda RX-8 seats but they looked a bit too "funky"
Excellent thread this which i can't believe I've missed. I started another thread on exactly the same subject ! My worry now is that it appears half of the site users are looking for replacement seats this week
Leather Saab seats came in our van. Far to high up, so sold them on eBay and replaced with non-leather MGF seats from eBay. Angle grinder to take of the unwanted bits from the slide rails, then bolted in quite easily.
