I am looking to buy a medium car that I can use for commuting on country roads (20 miles a day), driving around town, and regular motorway driving. The catch is that my partner uses a powered wheelchair (120 kg) which we would like to be able to take on trips at weekends. The majority of the time I will be the only person in the car, and so I don't want a specific wheelchair accessible vehicle. He would not want to stay in his wheelchair, and would sit in passenger seat. I have been looking at getting a car with a flat loading boot, so that with a ramp I could drive the powered wheelchair into the car. Many of the cars I have been looking at would need the back seats to be folded flat which suits us fine, but my main concern is that a car boot/folded seat would not suppor the weight of the wheelchair. Would appreciate any advice on potentially suitable vehicles?
