People worry to much about looks..
"off topic, but yet not",
I owned a 1966 Ford Truck at one time, it was the ugliest thing you have ever seen, but that truck ran like a champ. We had a blizzard one year, temps dropped real low, and all of all the vehicles down my block "new vehicles included" my old 66' was the only one that would start that day, faithful till the end it was.
"back on topic" Much like Ccleaner above, been using it for some time now, and it just works, has never caused a problem, so i could care less how it looks, i only see it when i run it to clean every once in a while.
