The original poster is making a great argument for the Feds to stop sales to untrained persons (and how many of us went thru a military driver's school?).
I believe the seller has a duty to completely disclose all he knows about what he is selling, be it a truck or mower or real estate. I also believe it is up to a buyer to be aware of what he is buying. I recently went to Budget and rented a truck close in weight to a deuce, but automatic. It was easy and they did not delve into my knowledge of trucks. Just sayin...
I don't think the argument would be made in the original post (through questions) as much as it could have been made in successive posts. A short time back a guy wanted to swap his old jeep for a duece, and allegedly struck the seller after being refused a sale (thread titled "lil' angry"). Do we have the integrity to say, "sorry, you look like a loser, I don't want to sell my truck to you (and also, your trade-in vehicle looks suspect as well, why don't you both make like trees, and leave.) Is that rude? Yes. Can it be the right thing to do? Yes.
I'm not comparing myself to any other members, but--if I get to the point where I would be willing to sell a truck that I really like, I would hope that I could still see it driving around town, or at least might spot it in another town when I travel. If I can picture seeing my truck on the front page of a newspaper, describing how the buyer had a terrible mishap while driving, that would force me to say "no deal", at the risk of the seller throwing a physical temper tantrum.
The same would apply to me purchasing a vehicle. If I can envision my name in the paper as a result of 1.that vehicle + 2.that seller then that equals=NO DEAL.
With regards to risking legislation against our hobby...we are a free, self-governing people. This thread should reflect that we govern ourselves, our hobby, and do it responsibly and voluntarily. This online assembly of people has NO CAPTAIN. It is privately owned and maintained, members are allowed to express themselves responsibly, and moderators overlook civility, technical issues, and keep out the riff-raff who cannot self-govern.
God bless the owner of this site. I am truly appreciative of what he has done.
