Yep, the lot here in Houston has over 100, I see very few on the streets and I am seeing them selling lightly used. I will not pay sticker for one new, I will wait until they start to discount them which is coming. The Quarter Master will take some of the spotlight away from the Grenadier as well which should incentivize them further.
I think your "discount" is happening now. For the first year Ineos allowed anyone to order a vehicle with a 100% refundable deposit. You didn't have to commit until the vehicle you custom ordered was on the dealer's lot and even then you could walk away without spending a penny. Most dealers in the US/NA got 500+ advance orders. Those have mostly been sold. All that's left on the lot are the orders that the "never gonnas" spec'd and a few dealer showroom models. The no-down-payment preorder option is gone and the 2025 base price has jumped with no significant model year changes ahead. In fact the starting price on Grenadiers has jumped almost 10% for each of the three years they've been on the market (they started selling in the EU and Commonwealth countries in 2022) so buy now if you can find a vehicle with the features you really want. The must haves are the high-load auxiliary wiring, the integrated tow package, and the lockers. None of those can be added after the build phase and there's no aftermarket locker option available yet. I guess you could swap in some Danas if you get a good enough deal.
