are deposits on vehicles from the dealer refundable?

Yes, true. If they do not refund your deposit then they cannot sell that car, that deposit entitles you to that vin. It’s as simple as that.

btw, you can have a deposit down to hold a car for a decent amount of time. I put a deposit down on my truck and then waited about 2 months until i sold my wrx before i went and picked it up.

Judging from Alpine’s conversation i would just pursue it, i have a feeling you’ll get it back. Best of luck to you
