Hi anyone out there had a problem with the interior door handle on their SL? My lever has broken inside the door. I have taken off the door card and a small section of the inner part of the lever has snapped off. Apparently you cannot buy this part - but have to buy the whole door card -£1200!! Does any one have a fix for this? I am tempted to try welding the handle back together but am worried about what the alloy is? Any help would be appreciated.
