The cybertruck owners club has a thread for a high use 10k mile production AWD CT titled with 2 owners. The numbers get a little messy as the insurance premium includes a 2021 Model 3.
They are paying $465/mo for both Model 3 and CT with $90k full coverage and the "highest possible deductible." For a comparison, they previously paid $205/mo with the Model 3 and a Ford Raptor. No mention of the Raptor's model year.
Another guy in the thread claims he was quoted $180/mo but gives no parameters and apparently isn't a CT owner.
We'll need to wait for normal AWD CT customers to get quotes versus the overpriced FS but it will still likely be more than what many want to spend given Tesla's traditionally high repair cost, the CT's unique design, and insurance companies not wanting to get burned.
