Interesting. I haven't heard anyone say that quite yet. It's only been a couple weeks thus far so I'm willing to hold out. I'm also open to W124s, an E420 sounds tasty but those are even harder to come by, at least around me.
I used to have an '89 2.6 back in Germany that had an LSD and getrag put in by the original owner. We couldn't take it back to the states, so we left it with my uncle there, who drove the car to oblivion back in 2008. Since then, I've been on the lookout for a car that was as nice as that one was.
I don't want an auto either, it has to be manual, and I don't want to go through the effort of swapping gearboxes, because chances are, that's not all I'm fixing. People buy and abuse these cars, so the mint-creampuffs are becoming nearly nonexistent, and when they do exist, they're halfway around the globe or the seller is a jerk.
I was looking at doing an M104 swap to that '89 had it survived, as there were plenty of donor W124s around for the motor, but that never came to fruition. W124s are great, but if I were to look for one, I'd just go specifically for the 500E/E500.
