For a extra$500 I could get 2 more years of warranty for poo. But the way I looked at in 2 years it would have boost to void the warranty anyways. But the T3 had options to lower the price too. A SP T3 in black is $750 less than the T3 x in red/ yellow.Kinda apples to oranges comparrison.What is cost of T3 163X with a standard 4 year warranty to a poo with 4 year warranty. You should find that an apples to apples will yield a price difference of under $400 on a 16K sled - pretty dam close.
More of a what do I like issue than a cost one on two dam fine sleds that few can push to either of the sleds limits.
In the end a guy could build a 174 axys for close to the same money as a T3. There are a lot of options when pricing I'm sure you could go in and price a T3 for less than fully optioned out axys. I thought it was good of poo to offer reduced price with less warranty.
