Can I show custom product options based on the vehicle the user has selected?
Yes bundle / kit products in Magento will have their options filtered based on the vehicles assigned to those products. In this way you can have a product or “kit” that is universal or fits many vehicles, and you can have different components in this “kit” that each only fit a handful of vehicles. In this way you might have for example a suspension kit that fits all “Ford”, but you might have different options only available on F-150s. Or certain options available based on the trim, engine, or chassis value.
