It had a button on the dashboard which when pushed, would shoot lubricating fluid through the car.
The weirdest car I had that really hid the gas fill was a 69 Renault 10. It was in the rear inside the engine compartment. The battery though was up front in the trunk. Very cheap car. Very expensive to keep running afer 30K miles.
That sounds very messy...
In 1957-8 (for two years)my 34 Packard 4 dr. Phaeton had that and thermostatically controlled grille vents, push button lube and Shock absorber control from inside car.
The engine was a straight eight with an aluminium block, aluminium transmission case and a stainless steel head. The differential was huge but tilted to achieve a lower body height!
From a dead stop in third gear it had torque enough to walk away and up to speed!
Mercury Turnpike Cruisers (57-58) had air intakes in front roof pillars.
My girlfriend had one of those.
Only not on her dashboard.
Gee I miss her sometimes.
