Custom fields for posts

Hi there,

I’d like to have a Section/Category on my website where I post different items with the same description format.

Let’s say the category will be about cars, so I’d like to always write a post about a car like the Camaro xg88, just saying, and I’d like to have fields where I put it, year, designed by, color, power, etc.

I’d like to have these same fields and same structure for the post every time I make a new one. Because I’d also want to add a Refine Button to this category where you could chose to see the posts by year, color, model etc…

What is the best way to make this happen? please be very specific I’m new and clueless 😀
Even if I won’t be able to do it myself and I’ll go to a web designer I want to know what to ask for!

Thanks a lot
