The diesel truck is useful…
The diesel truck is useful for the business. It can pull a trailer filled with roofing supplies. Do that with a Cybertruck and you will apparently rip the hitch receiver off.
That said, if they show up in a lifted brodozer of a diesel "work" truck with every accessory from Truck Toys bolted on, I'm not hiring them either. I'm fine with you making a profit, but if you're making enough profit to make your truck a less useful vanity statement then you don't need my money.
