I sold 25 model cars from my collection last month before I left China, those models were left behind because:

1. They are not 1/24 scale, all of them are 1/18, I personally prefer 1/24 premium quality model cars, so had stopped collecting 1/18 long time ago.
2. Some of them are manufactured 20 years ago, such as those from Lane Exact Detail(a.k.a LED), the build quality at that time is not top notch.
3. Although some of them have extremely hign standard quality control, and because of that, they have super high ROI if considered as an investment, I never thought collecting model car will became an investment at the time I won the biddings on eBay, so why not, such as CMC 1961 Ferrari 250GT Berlinetta Passo Corto(SWB) and GMP 1970 Plymouth GTX, I got incredible returns from the sale.

25 is only a small portion of my diecast model collection.
