Lovely car!
But any talk of it being better than the Plus Six is misguided IMHO.
The CX platform is in a different league to the old ali chassis on that car and I wouldn't buy it on those grounds.
There really is no comparison between the handling of the two cars and everything else is basically what you want it to look like
Indeed, a Speedster is going to be a "it's how you want to look" choice - but I'm not sure the CX car will be the nicer car to drive.
While Aero & CX chassis are leagues ahead of Trads, I doubt there's much difference in the chassis abilities between this Speedster's Aero chassis and a CX Plus Six - the CX might have a theoretical edge, but it'd be lost to being that bit harder to exploit. I reckon you'd have less confidence in the Six - losing it somewhere between the Six' well-known difficulties under acceleration making it hard to consistently get the power to the road, and Morgan's preference for trad-style suspension setups. In contrast, the auto box suits the V8, encouraging progressive power delivery without surprises.
And of course an SSL suspension improves both cars. :-)
