Depending on the size of vehicle you need, we would suggest looking at cars such as the Skoda Kamiq and Toyota Yaris Cross. These are small crossovers with slightly raised ride height, which makes getting into the driver's seat much easier, and are available with a choice of frugal engines or in the case of the Toyota, hybrid petrol. You may also wish to consider the Honda Jazz, which is a highly efficient hybrid, and while it is a hatchback rather than a crossover, it has lots of interior space for its size and is easy to get in and out of.
