First Capn', yes! The 500E/E500 is a whole other machine - Porsche had a large part in developing it, though is largely made-up of Mercedes-sourced parts (more robust drivelines, slightly differnt M119 engines, more agressive transmission gearing). I was looking for one for awhile, but exclusivity makes them harder to find, and I didn't want to pay the insurance and higher fuel-consumption costs. But I say, if the 400E impressed you, the 500 will astound even further
Check the hot-rod forum - there are several members there very experienced with these machines.
Actually, it's my understanding that engine wiring harness issue affected both the 6 and 8 cylinder models though it should be noted that some have no probelms at all with high mileage, so it's kind of a crap shoot. One good thing is, these cars are starting to get some higher miles on them, so a well maintained example could already have had it done.
I hear many folks here say that the M119 V8
needs new timing chain and tensioners every 100k regardless, but I have a slightly different view based on some respectable tech-opinions: the timing chain, if properly maintained (read: regular oil changes), has
no recommened change interval from the factory. It's a very durable system. Now, it certainly is wise to have them
inspected at 100K or so, but if it isn't worn or doesn't show any stretch (or is within specs), I don't think replacement is a necessity. I should also add that if the tensioners are badly worn and need replacing, the cost of a new chain is minimal and probably should be replaced while the thing is taken apart. I think a chain/tensioer replacement will run you about $1500 p&l from what I've heard around here.
Let us know what you go with!

PS, that's a good point sixto - head gaskets and wiring harnesses
aren't cheap fixes! I was just ready for a bahn-burner when I started shopping a few months ago. El presidente said it best buy whatever stirs you sould, but get the nicest one you can afford, with the best service history!
