Car rentals right now are really expensive, especially for minivans and SUVs, because the bankrupt or on-the-edge car companies unloaded cars during the pandemic, sometimes under bankruptcy court mandate, and now, everyone wants to travel!
That being said, Turo is going to be a lot like Airbnb in terms of reliability. If you choose someone with great reviews, that should give you confidence. A lot of people will bring you the car at the airport (for a price, of course). If you can reserve a big vehicle (minivan or SUV) this way, for a lot cheaper, I would. But I would also make a refundable backup standard reservation, just in case they cancel or don’t show.
