I paid $45,000 and my car had 3 miles on it so you offering $42,000 is what I'd offer plus they added shish that you didn't ask for them to add. Tell me to take the $42,000 or you go elsewhere. Good luck bro.
I just picked up a new '18 401A shadow black M6 the other night and the trans shifts smooth as butter without ANY issues, grinding or noises what-so-ever.
I originally went to pick up a 300 base model but left with the 401A digital dash blah, blah, blah. I didn't care about the active exhaust...
VERY easy system to install. The only thing I don't like is the harness is too long for the S550. It seems that the wiring was designed for the S197 in the trunk fitment. Either way it went in without issues and works as advertised.
I don’t know if they will fit the 10R80. The Gforce is lighter mainly because it is 3.5” whereas the DSS is 4” and heavier. I’d imagine the 3.5” DSS is about the same in weight though.
