You should follow up with the salesperson asking the direct question: "Do I have a custom order or are you awaiting an allocation".

It doesn't sound like you have a custom order in the queue but I can't guess at that any more than you can.

What makes you think it IS an order? Did you specifically say "Hey buddy this is Mike, it's been a while, I'd like you to place a custom order car for me, great thanks!" Or was the salesman like "Mike who, never mind, I have your number and I'll let you know when something is available"

You can't say the person you first spoke with wasn't knowledgeable as you hadn't talked to him since you "placed an order".
It sounds like you made an assumption based on a brief conversation and no follow up.
He was not technically wrong saying you have an order, it just isn't a custom order.
