Buy new car now or wait?

We've been waiting for a Toyota RAV4 Hybrid (non plug in) for over 1.5 years. We finally got the call that one will be available in Sept. It's not the one we ordered but a cancellation. Given the current interest rates does it make sense to wait for demand to drop and prices to come down?

We would be paying cash so interest rates don't matter personally. Our current car is a 2007 Mazda 3 and running fine but might need major repairs at any time.
