Those Peterbilts are very ugly in my opinion, I know there are different version of Peterbilts, I don't know the model name of it but I'm talking about the one that has a very long and square hood, and the headlights are very small square, and because they are shorter in height so the exhaust pipe stand out very conspicuously, so I think they are ugly, but somehow I feel like they are some kind of rude strong old beasts, and they also have a lot of marker lights put on them, it stands out especially in the night. I don't know if these Peterbilts are older model or not but if they are current model then it's not a very modern style types of truck in my opinion.

Now the International 9400i is ugly too, the headlight is small square too, but not as bad as the Peterbilt I mentioned above.

There's another kind of truck, I've seen them before but they are very rare, I don't even know the name of it, but they are perfect square, and it seems like they got no hood, just a small, square form, uglier than the Peterbilt. Anyone know what truck it is? Because it got no hood, if this truck hit something head on, I bet the fatality rate for the driver is much higher than any of the other common brand name trucks.

Some of the grander looking trucks in my opinion are Freightliner, Volvo.
Volvo's got a large headlight with a black shade, very stylish, and Freightliner's headlight's pretty good looking too.
Kenworths are alright but the mirror sticks out too much.

Again these are just my opinions, ugly trucks to me can be beautiful to you, so don't be offended if you are a truck lover and will defend your style of trucks.
