I checked my notes and quotes from shopping in 2011. I had two or three quotes each from Bobcat, Kubota and Kioti. The original Kioti quote had a $1,000 add-on item for "Assembly, battery, shipping and PDI". The Kubota quotes just had the total price and Kioti quotes after the first one still showed a line for "Assembly, battery, shipping and PDI" but the cost was $00.00. If you initially were just verbally discussing figures it may be an honest omission. But once down to a written quote I think they should include everything.
When I bought my truck in 2003 we haggled for a while over trade-in, options, etc. It got confusing so I told the salesman I wanted to see a final price with everything, including taxes, in. We agreed to that. Then they had an accounting person join to draw up the final papers. All went well until he added the British Columbia environmental fee (which is a tax for some hazardous or hard to dispose of things like tires, batteries, etc). It was not a lot, but I said I would not pay it. I had stipulated and received a price with ALL taxes in. The accountant continued to argue. However, a guy from the next office (turns out he was the dealership owner) poked his head in and called the accountant to see him. The accountant came back and said the quoted price was fine.
I think missing the environmental tax may have been a mistake on the salesman's part but I had been very clear on wanting the final, bottom-line price. The dealer did the right thing.
Looking at my old Kioti quote(which I bought 8 years after the truck) I see an "Environmental tire levy" at $00.00. This is because we eventually dealt on an "all-in" price and he adjusted his invoice to reflect that.
I suppose you need to decide whether or not the salesman was misleading you. I have always seen items like "dealer preparation", PDI (whatever that means), shipping, etc., on the few vehicles and one tractor I've bought new. That's why I always ask for a final "all-in" price. It is particularly important when comparing different brands.
If the salesman wasn't being misleading and you're happy I wouldn't worry about it. But you could use it as something more to bargain on.
