This is a really nice assortment of Aurora Thunder Jet track and accessories. This is a great way to get you started motoring in the slot car world. This comes with almost everything you need. Including power pack transformer, straight track curved, squeeze speed controls and accessories that are imperative to get you running. These tracks are used. They are all in very good condition. But you can expect to need to clean eraser the track. These have not been used in many years. sold as is. but is a great assortment of items. I will be listing different assortments that I put together, make sure you look at each one because each on is different than the other. all are marked SC-1 or 2 etc..... Thank you for your consideration.
