Might be worth looking at electric clutch conversions? I used to work for the Disabled Motorists Federation, and they had 2 shows a year of all types of cars/car mods. I have to have an auto, and one of the conversions I saw was a mk2 Astravan with no clutch pedal (hacksawed off), and a push button on the gearlever.
IIRC the mod kit was about a grand at the time, and could be transferred to any car. I'd look at one in the future, unless semi-auto comes into fashion for "basic" cars in the range.
On the 20 mile test drive, I can honestly say that Astravan went like stink..
