Finally took a closer look at the new car, and noticed a pool of radiator fluid in the recesssed area beneath the oil input (see photo). Radiator is fine. Fluid reservoir was quite low. Any suggestions as to how fluid got there? Does the intake manifold have to come off in order to see the culprit?
Check the clamps are tight on all the hoses, and if they are it's more than likely that it's the large O ring on the water bridge is the source of the leak, that's what mine was.

Reason: spelling
I first the little hose between the heater valve in the head and the fitting at the head. Then the heater valve. Then the fitting. Remove the whole air cleaner housing and look at the rear of the right side (passenger side on US cars...) head.
Free-rent a cooling system pressure tester from your local POLAPS, like Advance or O'Rielly. Pump the system up cold so you can find leaks without getting burned.
I'm regularly amazed at how many cars still have original coolant hoses on them. They do in fact deteriorate with age, and they often fail catastrophically. Inconveniently at best. Sidestep the bad experience and change them all, good for 10-20 more years with coolant changed regularly.

Radiator fluid pooled under intake manifold
