I have NO PROBLEM leaving the VX shop manual in the front seat, as well as ANY and ALL printed materiel that may aid a mechanic in working my VX. I rarely take my VX to mechanics, but for the few times I did, I always leave the manual and any docs in PLAIN site for the mechanics to see when they are working on my VX.
Hell, I would even say, "The VehiCROSS is a rare vehicle and most people have never seen one, and although I'm sure your mechanics know what they are doing, I left some specific information I would like them to review prior to working on my vehicle"
As long as you are polite and respectful, most mechs don't mind this. In fact, I bet having a shop manual on hand for a rare vehicle is helpful if then need it, even just for torque specs that are hard to find.
