Your ride looks nice. Well I have not hidden my seats under covers. Love their feel. This is my second car on which I have not put any seat covers.
I put seat covers on my previous Corolla and from zero meter to 134,000 kms and 10 years, I never looked at them again and never felt the coziness of the fabric. The next buyer also did not remove them, so what is the point? I will do get seat covers once the stock seats loose their coziness and look. In any case if you encase the seat covers with plastic wrapped and put leatherite or fabric covers on them, the seats will never come out in fresh look after years of use.
Thanks a lot.
