The YT450a was one of the very first designs of the Corellian Engineering Corp (C.E.C.) for the light freighter market. It sold quite well in the days of the Old Republic where it was released, but as C.E.C. quickly developed and released newer and improved freighters, the YT450a slowly lost its attractively. Free traders now preferred freighters like the YT1200, YT1210 and of course the famous YT1300 transport. There were some models between these and the YT450a, such as the YT700 and the YT1000, but they didn’t have high production numbers. However the freighters following the YT1000 were quite popular and still are! Especially the YT1300. They all featured better hyperspace and sublight speed, larger cargo bays and could easily be modified, things that the YT450a could not compete with.
