Another thing to consider is to look into having your MB Tex re-dyed if it doesn't match.

In my 300E (3.2) "E320" I had the drivers seat re-dyed after my wife left a tube of lipstick on the seat, which melted in the sun.

My expectations were quite low, but it ended up turning perfect....so perfect that I wished I had the rest of the leather re-dyed.

FWIW, I know that Leatherique sells leather dye, but it's applied with a sponge or a brush and rubbed in. The dye that my shop used sprayed it on out of a gun.

BTW, is your son still enjoying the car?
