Thanks Pezzy,Seems they were possibly able to get it to power up to pop it into neutral to get it on the trailer - either that or they dragged it up there with the rear wheels dragging.
Like others above said I think the leaving it stored for 2 months with the water still sloshing around in the floor boards is a big concern. Could you fly out for a few days to do some initial remediation? I know its still winter now but mid-70's in SC/NC won't be out of the question come the next month or so.
Good luck with this though - beautiful car. I was not a huge fan of this body style when it first came out but it grew on me over the years, my favorite S is still the W220.
The auction house loaded the S550 on the trailer with a forklift- that is how they load every vehicle that is sold. The Transporter was able to get the car in neutral, he actually sent me a video of him moving it back and forth on his trailer.
There is a ton to love about the W220s. I have two in my garage at this moment. The W220 is considerable lighter than the W221, and also has a smaller footprint. Makes for better fuel mileage and easier to fit in a garage. The issues with the W220 is technology, simply hard to have bluetooth, navigation, etc. It can be done but not fun. The other is they are getting old. My 2005 S500 with AMG appearance package is awesome, but at 210k miles it is getting tired. The seats are not firm, just overall tired.
I would stay with W220s until I died if the technology support was better, and I could have seats that were firm. But that is simply not so feasible.
