Pretty sad. The guy got all caught up in the fun and took it way too far. Get out of town on a highway to stretch the cars legs, not inside a city. The sales rep was probably just letting him have his way so he would be more impressed and maybe clinch a sale. No harm intended but 2 people died because of it. That guy will remember what he did for the rest of his life, horrible burden to carry.
REal sad what happened. That's what I was thinking as well, that the salesman wanted the driver to get impressed but that's insane, 100mph in a residential area. That's way beyond the scope of good judgement.
I know when I worked in a dealership a long time ago, 1 salesman told me of a time he took the customer up to 120mph, but that was at least on the highway. I'm not condoning irrational speeds of any sort but these salesmen areen't selling Toyota Corollas so they tend to push the envelope on the performance cars, but this was waaaaaay too much.
Very sorry for the people who died.
