Not looking great as it doesn't have the option to input my car (Mazdaspeed Miata).

However if you move past that you do have the option to input your model as the MX5, MX-5 Miata and Miata. You could argue that the car we are talking about has had all 3 of those names over the years, but it makes you pick a year first, so you should know what name it has in 04.

Then you move on to the trim!

Zero options for trim for MX-5 Miata. Zero options for trim for Miata. 31 options for trim for MX-5, including ones that absolutely were not sold in 04 including "Grand Touring Manual 1-OWNER! ONLY 7K MILES!".

Really bad user experience.
