I was going to mention Costco or Sams programs, but I wasn't sure if they did that in Hawaii. When I bought my 4Runner in Washington State, I went through Costco. They offered a set pricing on specific cars and a specific dealer. For the 4Runner, it was $1000 over dealer. That was when that specific model had just come out and the dealer just read off a price over the phone. I shopped around and none of the other dealers in the area could match or even come close really, so I ended up getting it through the Costco dealer. The "trick" was that there were a number of competing dealers within 1-2 hours drive, but with many brands here, there aren't as many dealers. Like Toyota and Lexus.
My cousin used to have a hook-ups with Audi and when I was looking, he mentioned that the way to do was through a mainland dealer/vendor. The competition there is great and many dealers are willing to sell at what dealers here can't even touch.
Good luck on your search. Hope you recover it or that you were insured. I had my car stolen when I lived in Seattle, but thankfully (more like unwitting luck), I was insured. My family friend set me up with insurance and she talked me into including theft and vandalism coverage, mostly for road debris damage, which is common in Washington. Only like $5 more per month, so I went with it. Well, I got more from insurance than I paid for my car. The car was actually recovered about 3 hours drive north of where I lived, but it was already after I was paid out for the car.
