The price difference is still there, new prosmatic oriel is 13k more without Navigation and seat covers which Grande is offering, so overall Grande is still 70k-100k less than civic top of the line model. I think Grande is overall nice package with Climate control added, new wow meter, 2 air bags, jack knife key and immobilizer, it has now well equipped.
At the moment Civic is highly overpriced car, with meh fuel economy and without navigation and leather seats, i think both should be offered as an standard equipment not as an add on.
