Car Parts Website - (Year/Make/Model) Filter - Must Categorize Entire Website by Part Type & Brand

I am looking for a completely categorized Word Press theme just like ...... [login to view URL] From a search standpoint I want a customer to be able to select their Year, Make, & Model and then have the option to select any category (such as Suspension, Performance, Body Kits) and have it then take them to another page where they can then click even more categories to find the exact part they need. Under each category it needs to feature a number of how many options are available for that category. So for Body Kits it would say (1998 Honda Accord - 2 parts). Or if they wanted to click a Brand Category it would also say how many parts are available for that vehicle under each brand. When a customer searches for a vehicle, they must be able to also use the search bar at the top and still have it remember their Year/Make/Model so it can easily navigate them to the right section, rather than them having to do another set of drop downs to select their vehicle again. This website will need to have parts categorized by Brand as well. So let's say the customer searches their Year/Make/Model, they must then be able to search by brand and have it pull up every part available for their vehicle from that particular brand. I'd like the broken down categories of parts to also be able to be used under each brand as well, so you can even break down your search to the exact part, by the exact brand you are looking for. I want a seamless website that is very easy to navigate and it always remembers the car that you previously searched, unless you physically enter a new vehicle in the drop downs. I want to maximize sales so I do not want this website to be unorganized whatsoever. Please make sure the Year/Make/Model filter is all alphabetized and that the Year range starts from 2016 at the top and goes down to 1950.
