What model do I have?
 

I have a white '94 with tan leather and sunroof. I don't have Bose, spoiler, or foglights. I think it's a base model with options but how do I find out for sure?

I would maybe try to call the dealer? I would imagine they should be able to get all that info for you using the VIN.

Sounds like it is a base model, because the only other model without the spoiler is the touring, and it has the Bose.

Definitely a base model.

for sure

It's definitely NOT an R model.
It could still be a Touring that a previous owner replaced the BOSE system on....something that I think was pretty common. That's at least as likely/possible as it being a base whose previous owner replaced the cloth seats with leather. Fog lights can be removed in about 5 minutes with a 10mm. So that tells you little.

Call Mazda USA with the VIN. They will tell you. Done.
