3-5k is a fair number for these spots.
I usually don’t shoot the car spots I edit but I have seen no reason to cut breaks as little as I do em so I just charge my hourly rate. Assuming you need a minimum of a grand a day for your time and overhead, thats how I started at 3k. A day of shooting, a day of editing and a day for graphics and animation.
That said, don’t let me make your day rate $1k. Figure up what you need based on your overhead and expertise.
