Its been raining non stop here where I live for the last few days, I just noticed today a rather large puddle in the back seat on the floor of my 2001 Neon. There is also some water in the spare tire well. Has anyone else had a similar leak? Where is the leak coming from? Somebody please help, I'm trying to sell the car and I dont think a big puddle in the back seat is much of a selling feature. Thanks
