I've been having a little dispute with some friends lately about which of my cars weighs more. I have a 1966 Mustang and a 2007 Mustang. Now, my friends and I are all gearheads and they seem to think that the '66 weighs more, but I'm the only one who has driven both cars and I'm pretty well convinced that the '07 weighs more. I'm thinking that maybe the bigger engine in the '66 might lead me to think that (the '66 has a 5.0L V8 and the '07 has a 4.0L V6) the '07 is bigger, but the '07 is a boat compared to the '66 when it comes to size. The '66 just feels a lot lighter behind the wheel and definitely looks it. Does anyone know for sure what the weight difference is? I can't find anything about it.
