With Flash, you lose out on so much SEO potential, which is why we steer away from Flash sites for dealers in the first place.
My recommendation is to go with the current web standards, lose the Flash, and get ready for a lot of obsolete websites for those who dont!
I certainly am not willing to write off Flash completely. At least not yet. Last I heard, Google is able to read Flash "words" as long as they are not images. Java Script can have its own problems, especially when it conficts with other Java Scripts... For example, when I create a new page in Dealer.com's back-end, I can't use Java Script because it conflicts with their system. I don't know how many other website vendors have that problem. But wait! HTML5 is coming out and is said to be able to do much of what Flash does, only using HTML. Let's wait and see. In the meantime, Adobe is a pretty professional company and may surprise us all with improvements to Flash itself....
1) Google cannot read flash words UNLESS whoever programmed the flash portion of your website has taken the time to have those words coded in such a way that they are discoverable by a search engine. Unfortunately, most flash that is produced for websites out there are not coded in this way because they were created by "click and shoot" flash development tools. You have to be able to dive into the actual flash code to allocate the words you want to have read by search engines.
2) Your customers really don't give a rat's ass about the fancy flash presentation in your website. Yes your menu has a wonderful glowing effect when a mouse is hovered over it and the speakers crackle with Star Trek noises but do you honestly believe that this has ANY influence at all in your customers deciding whether to buy a car from you? Not one bit. They are there to check out your inventory, see what your specials might be and to maybe check out your embedded Google map on where to find you. Other than that, all your fancy website huff and puff is little more than a guy dressed like a pimp trying to get a date with the prom queen. It just makes you look ridiculous. Keep your website simple and professional looking and you will get a lot more mileage out of it than trying to look like some jackass who has to have the largest Christmas light display on the block.
3) Flash is totally useless on things like the iPhone and iPad and other similar products. This is because they were made with a thing called "gestures" using your finger movements to control what is happening on the screen. Virtually all flash presentations out there are coded to rely on mouse-over interactions to make things like menus to appear and other similar effects. Since the iPhone and iPad don't use a mouse, every flash app out there that depends on this for navigation purposes or the like would be totally broken when viewed on any of these devices which explains one of the reasons that Steve Jobs refuses to allow it to run. With this in mind, the flash portion of every website out there would have to be recoded to work with gestures which is something that I am sure is not going to happen anytime soon.

What a wealth of knowledge out there, thank you all for your input. I use Flash in my website but I have never understood it's practicality over another option until this discussion. This is pure evidence of the immense value of social media! I'm listening attentively.
