Very well done car. I would probably buy this for around 1.5 - 2.5k. Don’t take my opinion into consideration too much though because I am very strict with how I spend my robux. I am sure you could sell it at 2-3k to someone.
I like the style, it’s pretty unique and looks nice as a low poly vehicle. Personally, I think your price hits the mark perfectly. If you were to add a couple little details I’m sure you could sell it for 5,000 Robux.
Honestly pricing is super subjective though, do what you see is best.
