Hello,
I ordered some floor mats for my 1996 VDP from Covercraft. In the area where you choose your vehicle, the only 1996 Jaguar that they had was the XJS. I chose a 1998 VDP. I figured that the floor mats were the same on the 1998 vs. 1996 Vanden Plas. What do you think?

 

Should be fine, the 98 will be a LWB so if yours is too then all good.
