Most downtowns (mine included) don't have car dealerships nearby. I have no idea where the closest one is. I suppose I could take a Uber to a dealer less downtown when I want to Carve.
All our cars are parked in valet lots downtown, so there's no need to go to the dealership + we'll give you $20 in Uber credit to get to and from the lot.
Looking briefly at their site, it looks like on some (all?) cars they offer an Uber voucher to get to/from the pickup lot.
