From Reader Sean F, his old car of choice, the Mercedes 770 / 770K of the late 1930s:
It’s a brute of a car (7.7-liter engine!), and heavy (especially when fitted with the armour plating and thick glass required by its most famous owner), but I’d take a slimmed-down non-Hitler version in a heartbeat.
And I’m just a sucker for those swoopy front wheel mudguards, in just about any car of that era.
