I've had mine done custom by a small company in my country.
You can choose between 3 different materials (i think the thickness differs), and i also got a small rectangular piece to cover the exhaust hump/tunnel in the back(really helps keep that clean).
No idea if they will ship to you, but it's worth a try.
Mine fit 100% in the front.. and 99% in the rear (they were fine after a few days..after a few feet stepped on them and made them conform to the shape of the car)
I chosed what seemed like the thicker material.. and even now 3-4 years later they are still great. I do change them in the muddy/snowy seasons with some rubber ones(they also sell custom rubber mats, and boot trays). But each time I put the carpet mats in, the whole car feel like 2 classes higher.
Can't you find a company like that locally? Not sure if it would still be cheaper than having them shipped over.
Mine were about 45 euro.
