Jump starting dead battery - where is the negative?

[DeeGee]

Hi. I am feeling really foolish but I am having a hard time finding the correct bolt for the negative. Is someone able to provide photos for me? I have looked at the manual and that is not very clear and have spent way too much time on the internet searching. I am hoping someone here can help quickly. 

I custom ordered my dream car in 2014 and it only has 20,000 miles on it. I love it but I do not drive it near enough and now lost with a dead battery!

Hi. 
if it’s the same as this one… the red capped terminal is the positive and the bolt circled is the negative/chassis/ground…. This is the one you need!

Unfortunately this is not what mine looks like 😞

Try these two!

Thank you I was thinking that bolt on the bottom left but am nervous to do damage if it is not correct!

Can you open the boot to reach the battery?

use this terminal to put power to the car so you can open the boot and jump it from the battery itself if I remember correctly
