Had a similar experience when picking up my 70D. I never could get an answer on how much it would cost to upgrade. I asked the persone upfront and they indicated it would be about $5K. I told them I would wait. When I got in the car and saw the dash indicating I was in a 75D. I asked was this something I was paying for? They went in the back and came and told me no extra charge. Great experience the first day with my vehicle and continues today.
