Powersports DMS
The big incumbents. Originally built for motorcycles, snowmobiles, and ATVs. Then bolted on a golf cart section.
Auto Dealer Software
Built for car dealers. Shows up in your searches because of keyword overlap. The data model assumes you sell vehicles with titles and VIN-decoded recalls.
Generic E-commerce
Shopify and the rest. Great for retail brands. Missing the things that actually matter for a dealer: rentals, trade-ins, lead pipeline.
DIY Options
WordPress, spreadsheets, the manual route. Cheap to start. Expensive in hours once you scale.
