1) For cars like Toyota and Honda when dealerships don't behave, Costco is a viable option. I've had good luck with the Costco new car program, and was satisfied I got my money's worth.
3) I don't like the Edge or the way it drives. Rent them from time to time. It's sub-standard, IMHO. They were steeply discounted for a while there.
4) I like the RX and the way it drives. Nice V6 too. There are times when Toyota's are overpriced and Lexus are discounted, nicely blurring the line between the two choices.
Out of what you listed, the Lexus would be my choice. I've always enjoyed the styling - I think it's the best-looking CUV (outside of BMW) on the market.
Yep I've bought out of state multiple times, and used too which adds the complication of needing someone else who I trust to give it a good look-over first...new you know exactly what you're getting. I wouldn't hesitate at all to buy it in NC since even paying for shipping you would still come out on top. That being said, I just bought the MDX across the country in April and I negotiated free shipping as a part of the deal so they have the ability to play ball in that arena, especially with COVID even more so.
The problem was, I had to pay CA registration when I bought it and they had to pay WA registration when they got home.
I had no idea... Kinda pixed me off; they shoulda told me during the negotiating.
What are the sales taxes like in OH and NC? You'll pay whichever is higher.
