I’m evaluating different automotive CRM systems for a dealership to manage leads, customer interactions, and after-sales support. Some platforms highlight automotive customer relationship management features like service reminders, personalized offers, and test drive scheduling.
For those who have used an automotive CRM software, did it genuinely improve customer retention and streamline daily operations? Which features proved most useful in practice?
