tbullard,
I see that you haven't posted here much and I'm not sure how long you have been lurking and reading posts, but I want to make sure you know why I'm NOT going to give you a dynamite sales pitch and tell you everything that is GREAT about DealerRater even though I believe very strongly in what we do and I'm confident you would have good success with certification.
DealerRefresh is the best of the best because the community largely self-regulates the sales pitches. This is truly an "Ideas" forum and unless you ask specifically about a product or company you won't see many Vendors successfully toting their wares. Also,
this search tool Joe created is awesome for this kind of research. Search and see what the community has to say, and you are likely to find Yago and I disagreeing about some of the things he's already posted in this thread like branded pages...

(trying to save us both from doing that one again.)
So let's talk about ideas:
I am looking to really ramp up my process and try to really start focusing on getting online reviews via dealerrater and so on. Does anyone have any best practices of how to get your customers to fill out honest reviews?
Kudos for seeking out the "Honest Reviews" not just the positive ones. You are positioning your store well to see immediate value. Too many vendors and consultants have popped into this space focusing on controlling a means to secure positive only reviews and they are missing so much of the value proposition. Again, search the forums for more info on this, but a negative review that improves your processes is NOT a bad thing.
Involve your team: DealerRater has seen a huge lift in submitted reviews after we implemented the My Reviews pages and started stack ranking the employees by review count. If the team understands that they are getting value from the effort you won't have to push it down on them and they become an asset instead of an obstacle.
Is it legal to give them something in return for filling one out?
It isn't a good idea to offer an incentive to the reviewer. What happens to the credibility of all the reviews that they read about you when they walk in and see signage that openly promotes that you are "paying" for them? "No wonder they had so many good reviews" is not what you want them thinking.
The other consideration is what happens when they feel differently after they leave. One post from a reviewer that didn't get their spiff due to a clerical error and you have a stiff breeze aimed at that house of cards. It is a much better play to spiff your team.
...we give them an opportunity to do one right then.
I'm going to start a new thread on the topic of collecting reviews in the store because it hasn't been discussed directly yet. I personally think it is counter-intuitive to ask a customer to write a review in the store and invites some unique challenges that aren't worth the payoff. More to come...
Last thought, I know you mentioned us by name in your original post so I'm assuming you have looked a little bit at the certification program. Feel free to call or email if want that dynamite sales pitch.
