Just last night I was updating my list of new and used MB parts. The list needs work because some items have a description, some have a part number, few have both. I have a dozen or so 015 997 94 48 o-rings. My best recollection is they go on an M103 EHA, the devil's engagement gift to his bride. Anyway, it's obvious I've bought and bought again stuff of which I already have a lifetime supply. If online stores want to provide value for all the personal information they collect and deduce, they should tell you how many you bought and how long ago when you add an item to the shopping cart.
