Reputable used dealers in the GTA

I’m looking for reputable dealers in the GTA selling used Altimas, so if you know of some please let me know. I’ve noticed the dealers associated with Nissan price a little higher than the independents, do they generally move more on the price too, or will I be paying more than at an independent for sure?

Opinions would be appreciated (as long as you don’t direct me to Downsview Auto, that name has come up a few times and people don’t seem to say nice things about them).
