I heard that the bumper regulations were an easy fix to make "legal" for the united states, it was the fact that mitsu didn't think that there was a large enough market to deem sellable here. When the WRX first came out and dominated sales, mitsu realized that it would be an economically smart move. Hence the battle between the evo and the sti. both companies are trying to "out do" each other. Both cars, are great deals for what you get, but eventually they will price themselves out of the appealed market. Too expensive for an asian sports car, like the supra turbo, 300zx turbo, rx7 turbo. As far as warranty, I have heard the same, but when I first bought my 01 gts, I bent two valves from a mis-shift (3-4) put it in second at about 85-90 miles an hour. Toyota knew what I did, and that I had abused the practice of "normal driving". They threatened not to warranty the damage ($5500). I made threats, writing letters to magazines, newspapers, etc. Telling about how toyota (and particular dealership) wouldn't honor thier extended warranties. Being as this was a somewhat common problem for the 2000-2001 models, Toyota decided to cover the damages. That is why the 02+ have a lower rev-limiters. Eventually this too will be problem for mitsubishi. So buy your evos now.
