Need a fun tow vehicle.... looking at a 2012 ML63 with 30k miles on it... we have a 4.6 bi-turbo in the E550 Cab and love it....
I've read the problems of the na 6.2 motors M156, not sure if the 5.5 has any similar issue ?
Thanks
Mike

I hope not!

The only issues I've seen are #5 cylinder leak from head and a turbo linkage issue. #5 exhaust valve seat elongates and leaks. Also turbo linkage for wastegate has excess play or broken off.
