I had bought this 1991 Cr-x in November of 2006. It has many problems that I am working on and fixed. I don't know a whole lot about any Honda but am learning. Yesterday, I took it in for some vinals and the guy had a Cr-x and told me I had an Si model, because of the door. The seat belts where built into the door is why he said that. When I got it, it had an HF badge on the back which made me believe it was and HF. Then I got thinking, I had Si seats in it but put Tenzo R's in it and the door panels had Cr-x on them. I am not sure but did the HF have any of the stuff like that. Seats had the red stiching on them.
