I have to laugh at these people who think a grill left in the elements is going to last forever. No grill does. I have had my grill a year now and it works as great as the day I bought it. It get's hot and slaps a mean sear on the meats. It's the best grill I have ever bought. It fires up every time and bam, the food is cooked. 
After three or four years I anticipate it will be time for a replacement and that's OK. I will have enjoyed many great meals prepared on my Broil King.
