In California, the legal age for riding in the front seat is 8 years old or older unless the vehicle does not have a rear seat, the rear seats are side-facing jump seats, the child safety seat cannot be properly installed in the rear seat, all rear seats are occupied by children under 7 years old, or medical reasons require the child to ride in the front seat.
You can drive a Jeep without doors but you better have your seat belt on.
In a certified car seat, in the rear seat- yes, convertibles have to meet a safety standard to pass.
The battery is under the passenger rear seat, you can jump start it under the hood and you can disconnect it just below the rear passenger seat. If you want access to the battery, you must remove the rear passenger seat. if its not under the hood check under the back seat or in the trunk drive safe
If it has brakes, seat-belts, lights, a working speedometer and odometer... if you can get it registered and insured than it is legal to drive on city streets and highways.... Good luck!
If there is an access panel yes otherwise no.
The rear seat is not designed to be removed. You can remove the center seat and slide the rear seat forward.
