I really like the tartan but I think the quality and appearance was a bit better in the MK5 and 6. Not to mention the seats looked nicer / more bespoke in those cars with the integrated head rests.
I think the material on the bolsters, sides of the seats and door cards lets it all down a bit. It feels a bit nasty and from what I’ve seen it stains and wears badly.
The perfect combo was something I optioned in a MK7 back in 2013, half alcantara / leather (on bolsters, door cards) with the tartan centres. No longer an option now.
