what interior color do you have now? Acura only made a couple different color mats for the 1st gen CL's. Depending on your interior color you maybe able to get the darker color mats off eBay or something.

If custom mats are ok with you, then go for them... I just love how Honda/Acura mats always fit sooo nicely... and their Honda/Acura badges add a really nice touch.
