Actually the seats are real leather, it was an option on the EX during that time period.I don't think the seats are real leather.
I read that some leathers have coatings (dont know what year it started) that don't require the (regular) application of conditioner. I think the idea is/was that most people are too lazy or absentminded to apply conditioner once or twice a year. The leather on my car's driver's seat is beginning to crack. Possibly not kept up by the PO.It doesn't...any smooth leather is the same.
I've used the pictured product, and it does an excellent job cleaning and conditioning.It doesn't...any smooth leather is the same. Suede leather is an entirely different cleaner.
Use any good leather cleaner/conditioner...many to choose from and usually, the higher the cost the better the product.
I use Meguiar's and it has worked well.
I hear you on the leather seats, but isn't putting sheepskin covers on it like jumping from the frying pan into the fire (lame analogy I know....first thing that came to mind). Sheepskin can be extremely warm. Granted, your not wearing it, but I think there is still a heat factor sitting on it.I have a 97 EX. It has a combo of leather and vinyl seats. In the summer it got too hot to sit on them so I just put seat covers on( Sheep skins)
