I am a seventy four year lady

I am a seventy four year lady. Retired. Bought 2003 Discovery new. Wanted dependable car.
Inside ceiling cloth has come loose. I keep cutting it so I can see how to drive. Heater in drivers seat stopped working.
Today, The vehicel overheated. 60,000 miles in a $42,000.00 vehicle.
Put anti-freeze and water in it four times trying to drive three miles to get home. Red light came on. Manual said stop and let vehicle idle fifteen minutes. Do you release how many mintues I sat on sde of road and used four gallons of water. Overflow kept shootng liquid out when top removed. Heater in vehicle puts out cold air. Vehicle smoked like it was on fire. My black rubber on front of car looks like someone has thrown up on it. How can a so called excellet vehicle have so many problems. Oh told head gaskets had to be replaced. Thands to the design of vehicle, I cannot check transmission fluid. Only someone with a lift to get under vehicle. Disc player under passenger seat. Temperature light has bottom out past cold and ho red light is on. I wish I could find the MEN that designed this vehicle and their wive had to drive it. It is not a dependable vehicle and is slowly fallen to pieces.
