I'm starting a new job soon which involves driving up to 50k per year and I am seeking advise on what would be the most comfortable but economical for such mileage. I'm currently driving a standard saloon Car but my back gets stiff and aches a little after long drives and i was thinking of a crossover / SUV but since I havent driven one i not sure if this would be a good choice for high mileage Tuscon, Tiguan and Hondas HRV are models that interest me in this category. The alternative is to go for a A6 or similiar... What would you advise ?
