Contacting manufacturers, discussing the requirements details, getting your shipment and listing your parts - the entire process usually takes about 3 weeks in the beginning. Once you start selling, the process becomes your second nature, and the profits start flowing. The more parts you buy and sell, the more profits you reap.
There is a list of factors, which will determine how much you will get for your junk car. Such factors are car's model, age, condition, etc. Obviously, the more popular and reliable models, like Toyota or Honda would cost more, as a lot of people own such cars, which means that their parts will be in high demand. That is why salvage yards offer more cash for car prices for this kind.
Now, admittedly, this information comes from the MSDS, and that deals primarily with bulk containers of the products, focussed and concentrated. However, those effects are still there when the product is diluted and used with other products, and you can also add the effects of those products into a nasty toxic chemical which you're breathing in as you drive, and your kiddies are breathing in too. No wonder the poor little tykes get car sick! They don't stand a chance!
Use your creativity, make something out it. Don't say that this is only for artistic person; everyone can create something out of a piece of crap. We've witnessed that some people would even make use toilet bowls in making a flower pot, and then why not use auto parts instead. Build a masterpiece out of a couple of junks from machines to car batteries, into a work of art such as metal sculptures. They who knows, some collectors would even pay you for what you've than, and you'll end up earning from this craps.
Needless to say, people never even used car seats or strollers of any kind back in the day. It may sound surprising, but mothers typically just held their babies in the passenger's seat when in a vehicle. In this day and age, you would be pulled over quickly for this. After all, it is not safe at all to just set a baby on your lap while riding in a car. Imagine if you were in an accident while flying down the interstate at 65 miles per hour. That could end very badly for the child. Anyway, this is why there are so many different new and innovative seat strollers on the market now. You can choose a model that is really suitable to your individual needs.
