Brownboy says it well- they've all got flaws I'm sure, but the first one sounds most promising.

I try to avoid accident cars unless it's obvious what was done, and they're cheap to boot. My 89 is a survivor of a deer hit, or some other similar light front end hit. I can see exactly what was replaced and it didn't bother me when I bought it.

My other cars are not prior wrecks so I don't worry about anything with them except warding off rust.

Likewise, you have to look for rust in all of these. The 7 series doesn't rust like the 240s, but can and will rust in the front fender/ firewall splash areas, and base of the strut tower and battery tray. The 2's can rust anywhere. Most common spots are under the front seats, either side, and all along the rocker panel. A car with rocker rust-through is not structurally solid. Avoid it. Also look at the panel just inboard of the rear bumper- they all can rust there, sedan or wagon.

Otherwise, 120K sounds very gentle on a car built for a half-million. Do the maintenance basics on it and enjoy it.

The 740 sounds like it's a 740 Turbo, not a GL or GLE. If it's actually a '89 GLE, run away. That's a 16 valve engine, and you don't want it. The turbo has its quirks, and leaking oil is one of them, but at least it can't grenade the head.
