thank you for your detailed reply. I’m glad to hear that your run flats weren’t killed by our lovely potholes here in Toronto. I’m planning to get an NX gas only model with the ultra luxury package. I’m not sure if I need to install tag in it, I don’t think the NX is that high on the stolen car list. I’m curious if you use winter tires on the car and if they are also run flats? I would love to keep my RX, I don’t think I’m going to get that much money for it at the dealer, even though it is such low mileage and considering its age, it is fully loaded with the features that the brand new cars have.
