Well gentlemen, the deed is done, I am now the proud (very proud) owner of an Appia S2.
I collected it from the Bristol area yesterday (could it be coincidence that my wife is away in Umbria for a week !!!!!!!) and I have not stopped smiling ....that is about buying the Appia, not the absence of my wife, honestly !!!!!!!!
Thank you everyone for your comments and advice about the comparative virtues of these two models. Having read and digested it all, I am certain that the Appia better fits the bill. I expect most of my mileage will be urban rather than rural and the feel of the Appia, the build quality and the sheer uniqueness of the model mean that all my expectations will be met. Having said that, my 150 mile drive home yesterday along the M4, M25 and A127 was excellent. Being new to me, I didn't want to push the car and the first 100mls was done at around 60mph, then a lovely session at about 65/70 followed by the tedium of the A127 at 55. Oil pressure and engine temperature were exactly what one would want, even in the inevitable queue for an accident on the M25 and at 65mph, the car responded readily when accelerated to overtake another vehicle. The exhaust note is great, helped I'm sure by the stainless steel system, so I have a car that looks great, sounds great and the way it goes belies its looks !!!!
Once again, thank you you everyone who has advised (and cautioned) me and hopefully I will see some or all of you at events through the summer.
If you want to see the car, please look for the Appia (the only one) present at the Auto Italia day at Brooklands, to be found on the Forum in 'events' .
Finally, thank you to Ben who so kindly and graciously sold to me one of his collection.
