What's the sign-up process as a car owner?
Easiest way to do it is to download the Hiyacar app and just sign up your car via the prompts on the app. You can also use a computer but you need photos of the car, which is why a phone is easier.
We've found it easiest if you say a bit about when your car is available and any restrictions you have in the description. Some people may choose to lend their cars for short journeys daytime only - that's fine, just say that in the description. Prospective borrowers will anyway probably let you know what they want it for - and I always asked, if they didn't, as well as checking if they wanted the car seats removing.
My car is generally available for borrowing evenings after 6pm and at weekends, however I commute with it so I need it back before Sunday evening 10pm. I am fine lending it overnight at weekends.
I have three children, and I leave the kids car seats in unless you ask me to remove them. I am happy for kids and dogs to be in the car.
