im having difficulty figuring out wether my car is 1987 or 1987.5 what are ways 2 tell the difference?

 

Look at you're manufacturing date..?

 

Look at the stickied FAQ at the top of the page.

Where?

Edit: Looking at the 2 brochures side by side.... but a manufactuing date would have been much simplier.

Edit 2: Comparing the standard features is pretty worthless because the only real difference is between the 87 Luxury Model and 87.5 SE (with is the renamed Luxury Model.)
