Hi Chris K, my wife is in the same situation, had her license for a manual taken away and had to do another test as she can only drive with a left foot accelerator as such she struggles to drive vehicles with a bellow type accelerator pedal.
She also needs a vehicle that is able to have a hoist fitted for her motorised wheel chair, as she has difficulty stretching she also needs a vehicle with a auto tailgate, so we are used to paying £2000 plus AP, with the recent rises in AP the vehicles we would normally look at are now in the £5-6000 bracket by the time you include the adaptions.
