83-84k with warranty.
73-74k without warranty.
Getting non warranty over warranty saves you only 12%.
But prices vary slightly.
You can visit Blue Area for non warranty new sets. Saddar is better for used sets. Non warranty sets, you better buy in person. The difference is so less than you better get the warranty one. Why risk 70-80k over a 10k difference for a QUALITY product?
Rather than new non warranty, slightly used warranty model can be bought for similar or even lesser price.
