As a long time reader of your column I do not recall anyone asking this question: Both my wife and I have leg trouble and need a car with a 'flat floor', i.e. one with virtually no door sill and an upright cabin for easy access. We have inspected numerous models, but apart from the Mercedes A-Class and B-Class they have all been rejected. We once had a Suzuki Wagon-R, which was perfect, but it had no springs.
