What happened to me on Sunday evening, I drove comfortably with 120 when there was suddenly a loud knock in the interior, then a “knall”, and I had once almost convertible (fortunately nothing else happened, the transparent plastic roof had dissolved in the bonding and hung still on a piece of glue firmly so very carefully, and immediately Monday morning very carefully to the SC. Result: new roof on guarantee (the old one was damaged), was now 4 days with a CDI loan crutch on the road and got my little one again today. Did someone like that happen before? At the 450s there were already broken glass roofs, but that’s why the “glass roof” at the 451s was made of plastic. Does the bonding not hold the current temperatures any longer? The hammer came then still in the SC, the SC had not at first a rented car before, then called the hotline from there, there one actually meant that I couldn’t get a rental ticket, I had to drive my smart again, the hotline again, and had to call it again, and then the SC got a little bit of a ride).
