If he's reluctant about giving you any numbers at all, go to a different dealer, absolutely. You're entering into a business relationship with this person. There's no reason to get a lease from someone who doesn't want to give every bit of information you ask for. Walk away.
Keep in mind that it's not just about the deal you work out today. You're going to be taking your car back into the dealership many times over the life of the lease. You don't want to be hassled about what's under warranty and not. Seems like you're setting yourself up for a 3 year headache with this guy.
