Used Car Dealer Liberty Inc. Implements Mico, Achieving Over 80% Conversion Rate in 5 Months Through LINE x DX Strategy

Mico Inc. (Headquarters: Kita-ku, Osaka; Representative Director and President: Osamu Yamada) announces that Liberty Inc. (Headquarters: Fushimi-ku, Kyoto; Representative Director and President: Koji Hasuo), which operates 30 used car dealerships mainly in Western Japan based in Kyoto Prefecture, has introduced Mico's LINE marketing tool and implemented a LINE x DX strategy, resulting in 20,000 LINE users acquired in 5 months. By promoting store visits via LINE, they achieved monthly sales of 83 units and a conversion rate exceeding 80%.

In the automotive sales and maintenance industry, "variations in conversion rates dependent on individual staff skills" and "non-scalable maintenance reception overwhelmed by phone calls" have become structural issues.

This initiative demonstrates that such issues of individual dependency can be resolved by redesigning customer communication starting with LINE.

A webinar will be held on Monday, May 25, 2026, from 12:00 to 13:00, where a representative from Liberty Inc. will directly discuss the initiatives and results of these five months. This is a co-sponsored seminar by M-Drive Inc., which operates an automotive industry specialized consulting business, and our company, covering a wide range of topics from industry trends to practical implementation know-how on-site.

—Those who register in advance will receive an archive delivery until May 31, 2025—

[Key points of implementation results]

1: Acquired 20,000 LINE users in 5 months. Rapid customer base construction through unified account management and review of on-site operations.

2: Achieved monthly sales of 83 units and a conversion rate exceeding 80%. Established conversions through a mechanism that grasps the temperature of prospects.

3: LINE-based store visit reservations reached 7 times the target. Promoted visits through continuous outreach to existing customers.

Background of implementation

Liberty Inc. operates a used car sales business primarily in Western Japan, based in Kyoto Prefecture.

At the sales floor, conversion rates varied depending on the skills and experience of individual staff, making it difficult to maintain stable sales capabilities across multiple stores. In the maintenance field, phone calls consumed a significant amount of effort, making it challenging to build a scalable reception system despite increasing reservation demand.

In addition, because only customers with high purchasing intent, such as those who made store visit reservations or direct inquiries, were targeted for sales, approaches to site-leaving users and potential prospects were insufficient. To solve these problems, they worked on redesigning customer communication using LINE to consistently support from acquiring potential customers to closing sales.

Results of implementation

(1) Acquired 20,000 LINE users in 5 months

Within just 5 months of introducing the LINE x DX strategy, the number of new LINE account users reached 20,000. The number of friends was expanded through a three-pronged approach: unifying LINE accounts that were spread across multiple stores, reviewing on-site operations to encourage LINE registration during store visits, and acquiring users who left the website. Account integration has enabled centralized customer management, building a foundation for sales activities.

(2) Achieved monthly sales of 83 units and a conversion rate exceeding 80%

They built a system to encourage users who left the website to register for LINE, and then, after grasping the attributes, interests, and sentiment of prospects through surveys, handed them over to sales. Conventionally, only customers with high purchasing intent, such as those who had already made store visit reservations or direct inquiries, were targeted for sales. By utilizing LINE, the number of potential customers was expanded. One factor behind the high conversion rate is the framework that allows information to be shared with sales representatives after understanding customer needs. Establishing "conversions through a mechanism" that does not depend on individual staff skills has directly led to monthly sales of 83 units.

(3) LINE-based store visit reservations reached 7 times the target

The monthly conversion rate for store visit reservations reached 7 times the target. By centralizing LINE account management, a system was established to uniformly and continuously deliver maintenance guides for vehicle inspections and services to existing customers across all stores, realizing a mechanism for continuous re-approach to existing customers. By shifting some of the customer follow-up previously handled by maintenance front desks and call centers via phone calls to LINE automation, they suppressed response effort while increasing the effectiveness of promoting store visit reservations.
