Similar experience - I've talked with a lot of drivers about their business, and perhaps 80% seem to have seriously bad models.
(One driver, though, knew everything down to the dime, and had a specific date set for retirement - he even told me how many years, months, and days it was away. That was an amazing conversation. He'd built and reviewed daily a big spreadsheet model, IIRC.)
For this driver, (s)he might retire rich. For the others, it's a question mark. It's useful to have a reference cost. i.e. the cost of driving a car is about $0.58/mile, the US government car mileage reimbursement rate.
