You should maybe add that your car is a 2012 one with its original chassis, the very early type without the small gusset plates in the corners. How many miles have you done since you got the car Hugo? I only ask as we both had a very close look at the chassis when you got it, then again when the lower wishbone mount cracks were discovered, only to find them cracked on your car. I would assume that MMC would have checked the chassis again when it was with them for the suspension point strengthening mods in 2018, not many miles ago. These cracks can obviously appear very quickly.
