Hi I can get mine in but they are tight! I tend to drop the small seat back down and put them in long ways!

How big is your golf bag?

standard cart bag

Perhaps a golfer should advise as I don't play so don't know sizes. Thought I might be able to help if you gave some dimensions.

A golf driver will not fit across the boot. you either need to take it out and fit it diagonally or put the small rear seat down. If you have a trolley you will need to take both rear seats down.
