Good to hear. I ended up with a spare as I replaced the interior in my last W168 with a full leather one.
Seat height adjustment lever ALWAYS brakes - every W168 I bought (not brand new) had one broken. It's not that straightforward to fit either, and some people end up braking the replacement ... Here's a scan of its fitting guide.
One of the other points to check (again, every W168 I bought, had that problem), is the air supply hose to the filter box: it is almost always split / damaged / taped over near the box (about an inch off); it is also quite often fitted wrong way round, as the diameter is the same on both ends:
Best place to get both parts, is from the main dealer - these are not expensive, and often cheaper, than anything from breakers / aftermarket.
Never had a problem with the grille, replaced the last one with an A210 type, but that was just cosmetic - the old one was not broken:
