Unnecessary upsell but super efficient location and service

Had booked a chevy Tahoe, was 'upsold' to a ford Expedition due to it having more luggage space at the counter by the Avis clerk and his supervisor who was sat next to him as I use a wheelchair and he said we would require the larger space. It turns out the chevy has more cargo space by aprox 6sft. I feel that I was just taken advantage of. The Ford was great to drive although it was dirty, windscreen inside was filthy and it was obvious it had not been valeted and was nearly but not quite full of fuel. Also the body of the vehicle was fairly beat up for a vehicle with only 25k miles. I did send Avis an email but disappointingly never received a response. The pick up and drop off was super efficient service
