"This is a special edition Gulf Racing DeLorean"
Now, one COULD order a DeLorean painted whatever color one wanted (within reason...for about $5K if I remember correctly)...so, I suppose this COULD be considered a "special edition" DeLorean if the factory in fact DID paint this one in the Gulf color scheme. But, I sure don't recall the factory having offered this color scheme as an "option". So, I'm calling "bull feathers" on the "special edition" moniker for that reason. I'd bet the farm someone simply had this done at a local shop one day...
(I still think a Buick Grand National turbo v-6 powered DeLorean would be a fun ride!)
