If you bought new stuff and now want to flog it it is classed as secondhand after you have used it regardless of time past.
I sold my traveling rig some time ago to down grade to what i have mow.
The Rig all up cost about $200.000 that is everything from the 5th Wheeler to the Iveco pulling it and accessories.
I sold the whole rig for $113,000 after 5 years, and was then asked by friends how much did you lose on the deal.
I said I didn't lose anything on the deal, they looked at me stupid, and I said I had 5 years of good service out of the Rig, traveled all over Australia covering over 70,000 kilometers, saw the most beautiful things the country had to offer and did the big lap twice, and had a great 5 years doing it, that cost me about $90,000 so i am even.
They didn't quite know how to answer that.
