A little late with a reply but i have contacted Ebay technical dept regarding the search issues when you look for SAAB 96..they reccomend if you only want those items to use speech marks..so.."saab 96" and it will only show items with saab 96 in the title. Not good enough! so they have phoned me to talk about the problems..i have made as few points about the fact that if i search for, lets say Vauxhall viva..i only get those items..they think it's because SAAB 96 has a number in the title and they are looking into it...who says eBay don't care?
Don't hold your breath waiting for ebay to do anything as I reported this problem/fault to them way back in march last year (Yup! the problem was there that long ago).
