2016 Mercedes E350 Deal...good or bad starting offer

I have been speaking to 2 dealers in Texas and have gotten this as the best deal so far:

24 months and 12k miles: 65% residual
.00130 money factor

The car I want has an MSRP of $62,360…What should my offer be?

I bought a car last year from the same dealer, a 2016 C300 and got 14.5% off MSRP. What sort of percentage should i deduct and try for this time around? He did tell me last year that Jan and Feb are their absolute slowest months, so that is a positive for me.

Thank you!

looks like a money factor and residual for a e400. you should use the calculator on the main site and plug all that information in.
