Magento: What is a good way to setup complicated product fitment?

Did you create the configurable product? A configurable product looks like a simple product with drop-down lists of options for each variation. Each option is actually a separate simple product with a unique SKU, which makes it possible to track inventory for each product variation. You could achieve a similar effect by using a simple product with custom options, but without the ability to track inventory for each variation. Products with multiple options are sometimes referred to as composite product. Although a configurable product uses more SKUs, and may initially take a little longer to set up, it can save you time in the long run. If you plan to grow your business, the configurable product type might be a better choice for a product with multiple options.A configurable product allows the shopper to select options from drop-down lists. Each option is actually a separate, simple product.The drop-down list values are based on attributes that must be set up in advance with required settings. The attribute Scope must be set to “Global,” and Use to Create Configurable Product must be “True.” The drop-down attributes must be included in an attribute set, which is then used as a template for the configurable product.The simple products associated with a configurable product cannot include custom variants or options, and must be based on the same attribute set that is used to create the configurable product. The associated products can be generated automatically from inside with configurable product record.The thumbnail image in the shopping cart can be set to display the image from the configurable product record, or from the associated product.For the details, please feel free to ask.

You need to add advance search attributes to your online store. I would recommend to use an extension which adds year, make, model, etc. attributes to your e-store. Have a look at this extension by FME - http://www.fmeextensions.com/magento-year-make-model-attributes.html

I don’t think you are on the right path. Can you please elaborate your question and explain in detail what exactly you want.As per what I understood, you have to define the right attributes in the column and when the consumer select wrong combination validations display it as an error. You should pass the right values, so once the entry is done by the user, it validates and displayed on screen.Go through this video for better understandingAlso, if you are just looking for a better product finding solution in magento, try http://zuvoo.com/ a new approach that most of the online stores are adapting.
