I have the Cobra Guzzlers and they are very fine drying towels. I have used them for many years and still have one or two I use occasionally. The link below will take you to the ones I use now. They are not advertised as car towels per se but can be used for anything, including bath towels. They are soft and gentle and soak up water every bit as good as the Guzzler. They are also very large at 24"x48". The biggest Guzzler is 28"x44" (I think) so you have essentially the same size towel but Neatitems microfibers are cheaper. The Neatitems do not have the hand pockets like a Guzzler but I don't mind that. They are very good quality towels but so are many others, including the Guzzler. But the big thing is, as I said before, they are half the price of the Guzzler in this particular size. Also, if I remember correctly, Neatitems offers free shipping if you spend at least twenty five bucks. That means you can get two of these towels for under $40 shipped to your door and I think that is pretty good.
Incidentally, if you go to the pool or beach a lot try their microfiber suede towels. They dry you off quickly (although they are not plush) and then dry themselves just as quickly. Just hang them over the beach chair or lounger and by the time you are ready to leave you won't have to worry about transporting wet towels as they will be dry in no time. Good stuff!
