It looks as though Towns was heavily influenced by his contemporary Harris Mann's design of 'the shape of things to come' Triumph TR7. And with a poor Cd of 0.34 (the bulky Audi 100 managed 0.30) it came......and went. A forty year old Auto Union streamliner would have swept past it. I can't see why it needs so much spending on 'restoration' as unlike my 40 year old unrestored fully functional TR7 it has apparently spent most of its life in pampered immobility. Aptly named - its canine namesake is poorly designed, requires much maintenance and likely to die early.

Seen something similar in style to the Hustler, IIRC (4-wheeled) in Turkey.

Think that was a local production car, and may not have any connection, just a 70's vibe thing, like the Bond Bug

(Quite hard to patent a box anyway, as I believe Landrover recently discovered).

Rare but a few still on the streets, I suppose due to simplicity and rust resistance of the body panels

They've got one in the Rahmni M Koc Transport Museum on The Golden Horn, well worth a visit if you find yourself in Istanbul.
