Package includes Mockingbird single to double stroller 2.0. All attachments included. (Mockingbird car seat adapter for stroller, replacement 2nd seat kit adapters set). Also Nuna Pipa RX infant car seat with the base. I only used the mocking bird stroller less than 5 times. It was probably used 3 times ever since I bought it. I don’t have a big enough trunk and this stroller is pretty big. Its in perfect condition. it cruises very smoothly even on tough terrain and its very spacious for any bags that need storage. The Nuna Pipa RX Infant car seat is in excellent condition. It stays inside the car and my drives are pretty short. I bought the car seat adapter so the Nuna can be assembled onto the mockingbird stroller as well as purchasing a second seat kit adapters set so I can turn the single stroller into a double stroller. Total amount that was paid to make this stroller into a double stroller (using the Nuna infant car seat was 975.00
