So I took my 96 land rover discovery off- roading, nothing too serious... lots of mud though... I got stuck several times and used my winch to pull myself out but then one time after i had pulled my self out it wouldn't start, at first it wouldn't even crank but after holding it for a few seconds it will start to crank again but will not start. I don't have a lot of experience with cars but there was water in the air filter which means water in the engine which isn't good. I had someone tow me home but I don't know where to go from there... and i'm not looking forward to spending tons of $ as i have already shelled out too much on this car. What should I do?
