I DD my 80.
My minimum daily round trip is 30 miles. I am frequently out to other shops, so my daily on those is 150 miles/day.
I average about 20K miles/ year.
I got my 80 cheap, I have gone through everything to make it very reliable.
You say "not safe"....I disagree. Look at some of the threads on here that people walked away from. Mines a 96 with dual airbags.
You say "not comfortable" I disagree. And I'm 6'-1" and a fat guy.
You say "not economical". I totally agree. But I don't drive it for the gas mileage. My cost per mile is very low due to depreciation and maintenance. WAAAYY cheaper than a new vehicle that can carry similar amounts of tools, inspection equipment, customers, and PPE as necessary. All that stuff doesn't fit in a Camry. The other guy I work with has a 2017 Chevy Silverado 3/4T that he owes a LOT of money on. I have about a fourth of the cost of his in mine. And he still seems to have issues with his truck needing to be in the shop. He get 18 MPG to my 13. I can buy a LOT of gas for the difference in investment and cost of fuel.
Plus, my newest vehicle is a 2009 Chrysler minivan, and I don't drive that one. Come to think of it, my LC is my third NEWEST vehicle.
I keep my stuff a long time and maintain old stuff with high mileage.
Plus, I don't have to worry about weather. Neither rain, nor snow, nor sleet shall inhibit me from arriving at my destination.
