Not that I don't like the stainless steel cover over the gas cap (with a mustang emblem on the inside) which looks very cool at that, but I was surprised that it wasn't locking or a pop out from the inside type. Granted, Ford had a budged in mind when designing this car and put the money in mods we all appreciate. I purchased a stunt locking gas cap for twenty dollars and like having that just in case some woodbee punk got any stupid ideas. I also purchased the LoJack system too, just for GP. I might sound paranoid but I do live in California which has a high rate of vandalism and theft . I don't know if many of you bought the cheapy alarm that Ford was offering but the LoJack and the locking gas cap seemed like the way to go for me.
