I'd agree with that, Kaimuki Toyota is probably the easiest to buy from, they seem to be just slightly more laid back and not so much high maka maka!
I guess the one I went to is no longer there, looks like it moved over by Ft. Shafter area. Used to be they were on Kapiolani across from the old Star Bulletin building.
And I had a feeling that Servco still supplies the non-servco dealerships with their vehicles, but its up to the dealership for pricing. If they wanna mark them down, that's their choice. Servco sets their numbers in stone though, so any servco-owned dealership will probably not have any flex in price of vehicles.
This is why I suggested following gotblika's advice in calling big island toy, if they do costco pricing, they obviously have enough flexibility with pricing to work a deal.
No, it won't be nearly as cheap as getting one from a big dealership in SoCal, but they might be able to get it down to the same or just slightly higher than the mainland price plus shipping (think its around a grand now? Could be low on that though) and another 500 bucks to fly out, as well as another 4 or 500 bucks for hotel and rental car.
So, if their pricing is more than 3 or 4 grand higher than mainland pricing, and you can afford the time to fly out and hit a few dealerships in SoCal, you get what you want and get to drive it around for a bit in the mainland before you ship it home, as well as pay for the cost of doing this! I'd say its a win-win situation right there!
