Lionel Freight Flyer Train 1987

first off I promise you will never find a nicer one than this I am 40 and was bought this for my 5th birthday my dad probably put it together two or three times for a day or the day couple hours maybe then it was put in a box put in the basement net at her to be seen again until now. I took it out it looks perfect and everything works and every single thing that was in that box is still there from 1987 this is a classic only serious buyers respond please this is some collector stuff and to be honest I really think it's cool and I don't want to sell but Biden's economy is killing me
