That seems like a lot. As others have pointed out, I would put away that 2k+ and fix the car if it ever breaks. 2K is going to cover a lot of repair short of transmission/engine swap.5 year / 60K mile MPP VSA w/ $0 deductible for $2650
Or, I can 'CPO' the car for $2100 which will provide coverage to 10 year / 100K.
cx9 isn't a Range Rover known for expensive repairs with needlessly expensive components like air suspensions. I really think you should just sock the money away.
