So, I appreciate the lengthy reply. However, I still think you're wrong. You've even seen the same stuff in America: the stories are out there, where a vehicle is marketed for the track or for off-road then gets damage from completing said activity, and at first (or, in total) the manufacturer refuses to honor a warranty. These stories are out there, though some companies have been forceful to come out to say, "no, track use will not void your warranty." GM did that for the Camaro and Corvette, for instance. To address your first paragraph, while there's no doubt that INEOS has repeatedly claimed (at least, not in North America?) that the rig is a work vehicle, it is unquestionably being marketed as a lifestyle rig. The many, many fawning reviews show this clearly. I absolutely suggest that INEOS should be making this clear, if they aren't, in the UK. This is tacit confirmation that it's supposed to be something...that it's not.
To your second point, you are also now seeing this in the US. I completely believe you that the dealers aren't asking you what you're doing with your commercial purchases. There's no doubt you aren't bringing an F650 to track day, but if you want to, go for it! Such capabilities trickle down. But you are seeing this, and seeing people make claims against dealers, regarding people selling F-150s for things that they cannot do, like an overloaded truck bed camper that wildly overloads the truck. In the one famous case I'm thinking of from this year, the purchaser specifically explained the role for his rig, and the dealer said "Sure!" and he folded his frame in half. I won't argue that dealers aren't garbage. Many/most are.
I am 100% certain that in the US, the way a vehicle is marketed is actionable, because it has been, time after time. To your stated conclusion after three paragraphs, I won't pretend to know how it gets handled in the UK. He could definitely get traction in the US.
Totally agree with the next paragraph. I generally agree with the last one, but it seemed like he was ready to buy the pickup? And I'm sure he was right that he could flip it and break even, or perhaps do better. People are doing that with Mavericks, so I'm sure it's true. I'd also like to know more about trim issues, but as the complete and total lack of service information here continues to blow me away I wouldn't touch one of these with a ten foot pole anyway.
