For reference: A RAM 1500 would pay 383 Euro in Utrecht as a person and 183 as a business (quarterly). And as a bonus you pay no BPM (aquisition tax) as a business, which is in the 12000-15000 (15k) range. The BPM hole has been fixed as of 2025 but there are enough already on the road.
I personally like the wanktank since it's more internationial.
You cannot use a "grijs" plate as a personal vehicle unless you pay "bijtelling" which starts at 500km yearly for private usage, but I guess the milage administration will be on the same order as the driving style.
Look at the license plates of these "tokkie tanks": they all start with a "V" (https://www.anwb.nl/auto/autokosten/grijs-kenteken) meaning the owner pays reduced tax.
