Given what you just said, why would you comply? Seems better to heed the Miranda warning "Anything you say can and will be used against you in a court of law" and just say "I'd like to talk to an attorney first". Whether you did what you're suspected of or not, given how the deck is stacked against you, compliance seems like the wrong choice and you may very well end up making things worse for yourself.
The cop is already pretty sure you did it (or he wouldn't have brought you in), so seems like there's little you can say that will change his mind.
What you're suggesting is what I mean by compliance.
You don't have to talk to them. It's probably the one thing you shouldn't do. You should respectfully refuse to answer questions, even before the point that they arrest you and read you the Miranda warning.
But you should allow a search of your vehicle. If you don't, they're just going to call a canine unit and provoke the dog to signal, regardless of whether there's anything in your car.
You should identify yourself if requested, provide proof of ID if requested, get out of the vehicle if requested, etc. Don't make any sudden movements or reach into your pockets. And smile.

There are different stages before arrest that matter here.
There is a burden of "reasonable suspicion", "probable cause", etc. (or some equivalent like "exigent circumstances"). An arrest requires both of these, plus some evidence of a crime. Being convicted at trial requires "beyond a reasonable doubt" (for criminal charges, as opposed to {civil, tax, military}).
