The reason why Ves put on a weird face right now was because of the presence of the supposed gold label Crystal Lord. The LMC's gold label products held a great amount of prestige that Ves had painstakingly built up step by step.
Ves sold relatively few gold label mechs ever since he went into business. He only sold around ten or twenty of them at a time because each gold label came with a guarantee of quality. Each customer who purchased a gold label mech would have absolute confidence of getting their hands on a mech that had personally been hand-crafted by the founder and lead designer of the LMC.
In other words, such a collectible luxury product shouldn't show up in some random mech plaza.
"250 million marks for this ultra-rare second-hand mech! It's an absolute steal to get a mech of this quality at this price!"
The seller was right on one thing. The mech represented a steal. The only questionable point was the customer might not be the beneficiary of the transaction.
