I have an uncle living in Mexico City that owns like 14 Mercedes, 1 Triumph and 1 Fiat.
He is not a member of this forum but next time I meet him I will ask him to sign. Don't even know how are his english skills...
His cars are not newer models, most of them are from the 60's, 70's and early 80's, but he keep them in pristine condition.
About twenty years ago he owned a SL gullwing for a couple of months, then another collector made him an offer he was not able to refuse and sold it.
I will ask him to give me a list that I can post later with more information about his cars.
