Knowing isn't something that you have much control over. You can try and know things, by learning them or finding them out or whatever, but whether you know something or not is a state of mind, literally.
It's the phrase go ahead and that gives rise to the oddness here. Without it, I'm going to know that's not your car, is fine. It means that in the scenario described, I will know a fact based on the evidence of my eyes, and my own knowledge and judgement of the likely circumstances (i.e. the car in a dealership is not necessarily your own; you'd probably take a photo of your own car somewhere else; pretending you own a Bentley is a plausible alternative to it actually being your car).
I hadn't realised before, but go ahead and is actually a peeve for some people. Internet people ask 'why do young people say they're going to go ahead and do something'. The answers tend to be along the lines of it meaning you have the listener's tacit approval, that no one has given you a reason not to do the thing, or that it's a more decisive, proactive action. In any case, all things that one needs to deliberately decide to do – to have agency.
And, as previously discussed, knowing something is not something that one can do deliberately. You can go ahead and reason that it's not my Bentley, you can go ahead and say that it's not my Bentley, and you can go ahead and assume that it's not my Bentley. But knowing that it's not my Bentley is a state you arrive at, whether you mean to or not. Sometimes, there are things one would rather not know – but you can't help it.
