Okay, so I really miss my E55, but I also miss my S500L. I am looking into getting either an S55 or a bi turbo S600. I really want to know your opinions on th epros and cons of these vehicles. I know they both need mortgages if they go wrong but what are the things to look out for? Mercedes Benz S600 V12 Bi Turbo | eBay This 600 is just gorgeous.
