Tamiya absolutely had a very nice Jeep Grand Cherokee kit, along with some other SUVs, that was very very nice and about the right vintage for you. It was in regular 1/24 scale too. I remember well, they had a full page add in Scale Auto, Fine Scale Modeller and I think other publications, with the about 5 or so built models sitting on a sort of rock setting. I thought the Cherokee was the nicest looking of the lot and was painted, I believe, a dark metallic green with tan interior.
I don't know if this is still in Tamiya's calalog, I might check out the web site myself, but they should stilll be available I would think at large well stocked Hobby Shops or ebay/online auction sites as well.
