Having many Google reviews shows prospective customers that a dealership is popular. A high star rating tells searchers that this dealership gives excellent service. A mix of the two proves that a dealership has many satisfied customers. In Chicago, we learn that the best reputations are made from a mix of strong review volume and high star ratings – not necessarily a focus on only one or the other.
- Marino Chrysler Jeep Dodge RAM earned the top-ranking spot in Chicago. This dealership excels with a high monthly review volume and a high adjusted rating. The #2 dealer, Volkswagen of Downtown Chicago, is just three points behind the top spot, and, with its high monthly volume, it has an opportunity to increase lifetime review volume quickly and reach #1.
- North City Honda has a strong response rate, the highest adjusted rating and one of the highest monthly volumes. However, its lifetime volume is limited. Continuing to drive many reviews per month could boost this dealership to the top spot.
- Berman Nissan has the second-highest adjusted rating, yet it places 6th on the list. That’s because it has a much lower monthly review volume compared to other dealers in Chicago. While this dealer gets great reviews, it should work on getting more reviews, perhaps by finding more opportunities to ask for reviews.
- The top 3 luxury dealers in Chicago are highly competitive with one another. McGrath Lexus of Chicago, McGrath Acura-Downtown Chicago and Perillo BMW each have similarly high monthly review volumes. Perillo BMW has a notably smaller lifetime review volume, placing it behind by several points.
- #4 and #5 on the list are falling behind in monthly review volume. These dealerships can find more opportunities to ask for reviews to boost the number of reviews they’re receiving per month.
- Marino CDJR earns its #1 spot for its high adjusted rating and high lifetime volume. This dealer has room for improvement in overall lifetime review volume, and it should work to boost its monthly review volume, so that the #2 dealership doesn’t surpass it.
- Interestingly, Honda of Downtown Chicago has the highest lifetime review volume but ranks at #4. This dealer risks getting surpassed by the fifth-highest dealer, McGrath City Hyundai, because of the Hyundai dealer’s high monthly review volume. To keep its spot as #4 or even move up, Honda of Downtown Chicago should boost its monthly review volume.
*Note from the editor. The Automotive Reputation Index offers substantial coverage of the nation’s dealerships, but it’s still growing. If your dealership is not yet listed on the Index and you’d like to add it, submit your information and we will add it during a regularly scheduled update, roughly once per month.
Widewail's rankings are based on the Widewail Automotive Reputation Index. Explore the full dataset:
Ranking Methodology
To rank these dealerships fairly, we chose a method that takes into account the fact that dealerships on our list receive a wide range of monthly review volume, in part due to varying levels of opportunity. For example, luxury brands simply can never sell as many cars as non-luxury brands, the price point limiting a luxury dealership's market.
To compare two dealerships with very different review volumes directly wouldn’t be fair. A dealer with two 5-star reviews doesn’t necessarily deserve to be ranked higher than a dealer with 200 reviews and a 4.5-star rating. With few reviews, the former doesn’t offer enough data for us to use to understand its performance. However, we couldn’t just ignore locations with very few reviews, as that would introduce bias into our rankings.
To solve this, we used "adjusted ratings" in our calculation of dealership ranking. In essence, "adjusted rating" is a dealership's star rating that takes into account how its review volume compares to that of other dealerships in that area. We calculated adjusted ratings by using a technique called additive smoothing which we explain below.
Additive Smoothing
The approach we’ve used is a form of what’s called “additive smoothing.” This process allows for an unbiased way to rank two otherwise unequal dealerships. At its core, additive smoothing levels the playing field by artificially increasing the number of reviews each dealership has by adding the same number of reviews of each star rating to every dealership.
Customer Engagement
Additionally, we take into account the percentage of reviews that a dealership has responded to in our calculation of ranking, as Widewail strongly believes that review response is indicative of a strong reputation strategy.
Activity
The last component revolves around how much review volume a dealership receives, which can be broken down into two parts - their lifetime volume and average monthly volume. Lifetime volume can be thought of as a popularity metric. It’s an important metric and one of the first numbers that a potential customer will see when they start looking at reviews. The second, average monthly review volume, is representative of how active the dealership currently is. We can think of it as follows, lifetime volume captures a historical view of the dealership whereas average volume gives insight into the current status. The final component for the volume metrics is to scale them so there is a more meaningful comparison. To do this we use what is known as min-max scaling. First, we group dealerships by their respective city and then find the dealership with the most volume and least volume. Then for each dealer in the group, we subtract the lowest volume and divide by the difference between the highest and lowest volume. The formula for this can be seen below.
x' = x - min(x)max(x) - min(x)
The main advantages of this approach are that all the volume metrics can be mapped to a value between 0 and 1 and the relative difference between dealership volumes can still be preserved.
Below we see an example of this where we have 9 dealerships with differing lifetime volumes, which we then scale. Notice that the relative distance between the actual volumes and the scaled versions is the same.
Below we have an example of ten dealerships, their review volume, and the adjusted relative volume. We can calculate the relative volume by sorting the dealers by review volume and determining the percentage of dealers that have fewer reviews. Here we see that dealer D had the most reviews and so they get a score of 1.

The Ranking Formula
(adjusted rating / 5) * 0.3 + (response rate) * 0.3 + (lifetime volume) * 0.15 + (avg monthly volume) * 0.25
Weighting Rational
We chose to weigh each feature as follows: adjusted rating accounts for 30% of the overall score, response rate also accounts for 30%, and review volume is 40%, which is further broken down into lifetime volume (15%) and average monthly volume (25%).
Weight selection is based on Widewail’s depth of expertise in the industry and we believe is a fair representation of what should be considered a standout reputation.
We’ve broken the weighs into three categories:
Activity (40%)
We believe the amount of review activity is the most important indicator of reputation health for a business, and is a leading driver of local search rankings. We’ve broken this category into two components: lifetime volume (15%) and frequency (25%). Lifetime volume is our “popularity” metric.
Engagement (30%)
Engaging with customers by responding to reviews is a key component of a healthy reputation.
Quality (30%)
The rating has a substantial impact on if a business shows up in local search and if that business is entered into a prospect’s consideration set. Rating is a key identifier of business health.
Calculation Details
If a company has an adjusted rating of 4.2, responds to 10% of their reviews and has an adjusted lifetime volume of 0.90 in their city and 0.87 for their scaled average monthly review volume, then we would calculate their overall rating as follows
(4.2 / 5) * 0.3 + (0.1)*0.3 + (0.9)*0.15 + (0.87)*0.25 = 0.252 + 0.03 + 0.135 + 0.2175 = 0.6345 * 100 = 63.45
Note: Since response rate accounts for 30% of the overall ranking, if a dealer doesn’t respond to any reviews that automatically caps the max value they can receive to 70.
