It's no Grinnall Scorpion is it?

Ignoring the distinct whiff of cheese from the video, I've always had a fondness for these vehicles (trikes with two wheels at the front) the styling is very much Xbow all things equal I think the Grinnall is a better looking machine

But the issue with these, bolt half a bike on the back, is around their CoG. The Morgan works because the engine is low and right in the middle of the front axle, so despite 3 wheels the car has good roll stiffness. This polaris shares a front engine configuration?

The Grinnall the opposite is true, the engine is mounted near the rear single wheel, which means the car has poor roll stifness. Its an even worse engineering solution than the 911's rear engined and deeply unattractive to me at least.

Why poor roll stiffness?

The single rear wheel AIUI effectively means zero roll stiffness, with the fron being setup however you choose (I've seen a single coilover setup with a rotary damper controlling roll).

The benefit, AIUI, being that you don't have two roll centres that are never matched, 'competing' with each other for effect on cornering...

As you can probably tell I'm not even a layman when it comes to chassis design, but I have been reading up on reverse trikes for a while - very few have a front engine.

Rather weighty for a 3-wheeler isn't it?

If the Morgan cost the same as this, I would already have a Morgan in my garage.

Her only thought was "What type of cock would drive that?"

In a bizarre coincidence, on the way home from work I saw a CanAm trike with rider and pillion.

Looked like a whole lot of fun, although I'd prefer car seating to bike seating.

This.

It's the first time for several years I have been pleasantly surprised by the price of a new car. Usually these days I am shocked how expensive cars have got.

I'd buy it, at half the price of a Morgan, a bargain, 2.4 motor should be quite strong too, if anyone knows of it coming up for sale in the UK let me know please.

Typical one second shot editing, like TV movie premiers or a bad movie making it up by shaking the camera - I turn it off.
Insult someone else's intelligence. I would rather have a golf cart that seats 6 and an ice chest.
