Interior: Brand new LEATHER. Major interior color change. Mercedes red, actually pebble grain, leather.

Battery is under the seat. Actually, two PC950s from Odyssey (sort of like the antigravity battery), so CCA is 1900 / batteries run in paraelle. Running a battery cable less than 10' is nothing ... that is why BMW as well as Mercedes do it. I am guessing their engineers got it right to some degree ... Plus, I used to have my battery in the trunk for over a year and NEVER an issue. That was one Group 49 battery with 17+' of cable, so not sure what "problems" that would cause.

As for the HE placement, WVO does not lose heat that way. Not really a subjective position, but just the chemistry and physics of grease. So, as for "heat loss", I would agree there is an academic amount, of perhaps a 10th or 20th of a degree traveling 35" or so, but I am not sure how 1/10th or 1/20th of a drop in 1 F is measurable except thru mathamatical calculations but I highly doubt felt by the engine itself. As for volume, unless you have a closed loop set up, heating a pint or less is generally not going to be providing on-call WVO at 170-ish. Further, the only real option is a thermaline which is coincidentially 30" long which is perfect for a straight away from the HE to the IP. Trying to wrap the TL on the injection lines is about impossible for me but fits nicely in one straight shot. Now, that is not the mythical solution either to get to 250F either, but you can count on another 10-20F, depending on the ambient temps.

I used to have a 30HE which was probably the most common HE out there. Fill it up, and then drain it out and add 10%. Assuming that is your volume, the om617.9XX fuel system will blast thru that amount in less than 30 seconds. Assuming no closed loop system, calculate one's heat loss going from the fuel tank to the engine and back.

So, in the WVO community, everyone has their own flavor and "best" ways of doing things which is why WVO is truly a personalized modification and preference. However, some things are subject to the rules and laws of physics. Heat transfer, heat loss, et cet., will be the same in my system as well as yours. Who knows, my last system was supposedly perfecto but I changed it after a few years. Maybe a Greazzer 3.0 down the road.
