I'm looking to buy a 2025 or 2026 mini countryman and the dealers near me have some for sale that were demo vehicles. They are giving discounts of $7k to $8k which seams like a good deal. Has anyone bought a demo car from mini before? Any concerns I should have or questions I should ask the dealer specifically about it being a Demo? Some are CPO while others are not. Any advice is much appreciated, thank you!
