My interior is black MB tex, and I have to admit it just looks like new, not bad for a 43 year old lady !
Apart from the smell, there ´s almost no way you could tell the difference from leather.
To be honest, one sit has a tear I made myself when leaving a scewdriver in my rear pocket (oops!), but I am told this is an easy fix, as there are repair kits for MB tex.
Even the upholstery shop I contacted told me to hold on with vinyl, but if it were totally ruined, I might go for leather instead, and opt for a different color as beige or grey...
