Most sought after and desirable it most certainly is. But call me a heathen - a four speed box with no synchro on first (also used in some XK Jags and early E Types).......... no thanks. I'd rather have a modern five speeder.
The Moss box was an intersting installation though, with the bellhousing & clutch conventionally placed, but then a torque tube with the gearbox mounted directly under the stick - almost between the seats. This layout was common prewar and the flat rads also have this layout (no doubt some vary).

There's a general trend for the first of the line to become most sought after - partly due to survival rates and supply & demand. The MGB suffers from this, despite later cars being much improved, as does the Alfa Spyder (although in this case the first series is probably the best looking). So it's not unreasonable to expect the Aero Series 1 to follow the trend, and who knows - maybe the Roadster Series 1. Fingers crossed.
