Here's a question I hear all the time from auto shop owners:
"How many reviews do I actually need?"
It's a fair question. You're busy running a shop, not obsessing over Google. You want a number—a target to hit so you can move on.
The answer depends on a few things. But I'll give you the benchmarks that actually matter.
The Trust Threshold
Auto repair is different from other local businesses.
When someone needs a haircut, the stakes are low. Bad haircut? It grows back.
When someone needs a mechanic? The stakes are high:
- Expensive repairs — A transmission job can cost thousands
- Safety implications — Their family is riding in that car
- Fear of being ripped off — The industry has a reputation problem
That means customers research MORE before choosing a mechanic than almost any other local business.
So how many reviews do you need to clear that trust threshold?
The Benchmarks
Here's the breakdown based on what I've seen researching this space:
- Under 10 reviews: You look new or sketchy. Red flag for customers.
- 10-30 reviews: You're credible. People will consider you.
- 30-50 reviews: You're competitive with most local shops.
- 50+ reviews: You stand out. You look established.
- 100+ reviews: Diminishing returns. More doesn't help much.
But here's the thing—the number alone doesn't tell the whole story.
Quality Beats Quantity
For auto repair specifically, quality matters more than raw numbers.
Why? Because the stakes are high. People read more carefully.
Shop A
200 reviews
4.2 star average
Mixed recent feedback
Shop B
45 reviews
4.7 star average
Consistently positive
Which shop would you trust with your car?
Most people pick Shop B. The higher rating and consistency outweigh the raw number.
For high-trust services like auto repair:
- 4.5+ stars is the target
- Recent reviews (last 3-6 months) matter more than old ones
- Detailed reviews build more trust than generic "great service"
The Real Target: Beat Your Competition
Here's the most practical advice:
You don't need the most reviews in your city. You need more than the shop down the street.
Pull up Google Maps. Search "auto repair" in your area. Look at your direct competitors—the shops within a few miles.
How many reviews do they have? What's their rating?
That's your benchmark.
- If they have 30, you need 40.
- If they have 80, you need 90.
- If they have a 4.3, you need a 4.5.
Reviews are relative. You're not competing against every shop in the state—just the ones your customers are comparing you to.
Why Auto Shops Struggle With Reviews
Most auto repair shops I've talked to have the same problem:
They do great work. Customers are happy. But they only have 15-20 reviews while the competitor has 80+.
Why?
They don't ask consistently.
Auto shops are busy. Cars come in, cars go out. By the time you remember to ask for a review, the customer is already home and has moved on with their life.
The shops with more reviews aren't doing better work. They just have a system for asking.
The Math
Let's say you service 40 cars a month.
If you ask every customer for a review:
- 15-20% will actually leave one
- That's 6-8 new reviews per month
- 72-96 per year
In 6 months, you go from 15 reviews to 50+.
In a year, you're at 100+.
The math works. You just have to ask.
The Revenue Impact
Does this actually matter for your bottom line?
For an auto shop doing $500K/year, a 1-star improvement could mean $25K-45K in additional revenue.
Even going from 4.2 to 4.5 stars makes a measurable difference in how many people call you vs. the shop next door.
The Bottom Line
How many reviews do you need?
Minimum: 30+ to look credible
Target: More than your local competitors
Rating: 4.5+ stars
Recency: New reviews in the last 90 days
After 100 reviews, focus less on quantity and more on maintaining your rating and keeping reviews fresh.
The shops winning on Google aren't necessarily the best mechanics. They're the ones who made getting reviews part of their process.
That's the difference between being the shop people find and the shop people drive past.
Frequently Asked Questions
How many Google reviews does an auto repair shop need?
Auto repair shops need a minimum of 30 reviews to look credible to potential customers. The ideal target is to have more reviews than your local competitors with a 4.5+ star rating. Under 10 reviews makes your shop look new or untrustworthy. After 100 reviews, you see diminishing returns—focus shifts to maintaining your rating and getting recent reviews rather than raw quantity.
How do I get more customers for my auto repair shop?
The most effective way to get more customers for your auto repair shop is to build a strong Google review profile. 72% of consumers won't choose a mechanic until they've read reviews. More reviews with a high rating means better visibility in "auto repair near me" searches, which directly translates to more phone calls. Focus on asking every customer for a review and responding professionally to all feedback.
Why do auto shops struggle to get Google reviews?
Auto shops struggle with reviews because they're busy with cars coming in and out all day. By the time someone remembers to ask for a review, the customer is already home and has moved on. The shops with lots of reviews aren't doing better work—they have a system for asking consistently, usually through automated follow-up emails or texts sent after each service.
Do Google reviews actually increase revenue for mechanics?
Yes. According to Harvard Business School research, a 1-star rating improvement leads to a 5-9% revenue increase. For an auto shop doing $500K/year, that's $25K-45K in additional revenue. Even smaller improvements (like going from 4.2 to 4.5 stars) make a measurable difference in how many customers choose you over the competition.
Is star rating or number of reviews more important for auto shops?
For auto repair shops, star rating matters more than raw review count. Because auto repair involves expensive services and safety concerns, customers read reviews more carefully. A shop with 45 reviews and a 4.7 rating will typically beat a shop with 200 reviews and a 4.2 rating. That said, you still need at least 30+ reviews to look credible, and recent reviews (within the last 90 days) carry more weight than older ones.
