Looks like a conversion vehicle. There were some companies that would take new vehicles & modify them to be sold through various dealerships.
Usually the mods included, but not limited to, running boards, visors, vinyl graphics, aftermarket wheels +/&/or interior 'upgrades' such as woodgrain additions along with aftermarket seats, such as in that vehicle.
Those seats look like the ones from a Co. called 'FlexSteel'. They're just O.K. While they may look nice, the actual construction of those seats is not what I would consider equal to factory quality.
If they are covered with leather, the leather is of a lower grade than the factory GM stuff.
Too soft of a foam base that deteriorates sooner than the originals.
The 'springs' are not actually springs. They are nothing more than 1/2" plastic packaging straps. The same as what's used to wrap around boxes when being shipped. Yea! The designer used the softness of the foam for that comfy feel, with the straps merely there to keep the foam suspended.
I've repaired & rebuilt many of this style. I like to ditch that stupid strap design & replace them with proper 3" wide elastic webbing specifically made for upholstery.
The frames are made of mild steel tubing. They have a tendency to break at the bottom rear. I've had to repair/weld many.
They do not have a recline feature.
If they have heaters in the seats, they are not the best quality. If they work consistently or even at all, they can be prone to overheating. It's 20-25 year old tech. Seat heaters have come a long way in design since. This can lead to multiple problems, resulting in anything from melting the foam, burning up the covers, or the occupants butts.
Not saying that the seats are complete junk. Many people love 'em. They are comfortable. But, just be aware that they are not OEM quality.
When they do need work, they can be upgraded fairly easily.
So basically, they're pretty on the outside, ugly underneath.
Kind of like some women I've known! Lol!
