That's an interesting opinion, and you are entitled to hold onto it. I am very content with my response.
"Do your research" is not a helpful suggestion. I am doing research, right now. That's the purpose of this thread. When I got this USED CART as part of a PACKAGE, I did my research. I got a screaming deal on three items. It was a huge bargain. I could not ask the seller to give me a Kubota instead of an E-Z-GO. He didn't have a Kubota.
I needed a tractor, a mower, and a cart, fast, and this guy was selling for about half of what his were worth. I was very busy with a move and taking care of a dementia patient. I did not have time to scour the state to see if some other stranger would basically give me $10000 and hand me exactly what I needed.
Now because I have done more research while I owned the cart, I am doing new research because I may want to get rid of it and get something better.
Because I researched, I know I can sell the E-Z-GO and put myself in a big Kubota diesel with low hours for about $4K. Now I am researching things like ground clearance to see if the Kubota will work
Kubota isn't going to give me "a back seat" if I order a part for a Kubota UTV. I don't know where that came from. If you want a Kubota part, you ask for it, pay for it, and take it home. Nobody asks if you have a fleet or whether you also have a tractor.
As for Jacobsen-GO's poor business practices being "on me," well, that's a novel theory. Ordinarily, companies are responsible for their failings, and customers are not.
If their failings are on me, then my choices to show them up on public forums, Youtube, and my widely-read blog, and to buy someone else's products, are on them.
