add more polies, and make sure the diagonals all face the same way. The simple way to do that is click the second box along, unselect 'SEL' on the bottom right and click on the relevant box.
ur help is appreciated fongu. ill probably wont be creating more polies yet as i just want this to be a quick car i can make just so i get used to the process .
what do you mean by 'click the second box along'? i can see the SEL key though and it is currently not selected.
