I highly doubt that, however there old 4 liter based jeeps were known to go over 300k without a rebuild and no major repairs. So quality was a jeep thing, can't really say that with the newer models though.
Kudos to Chrysler for finally making their products LOOK like a finished product ready to be on sale. I won't comment on long term durability, but at least now they dont look like matchbox cars.
I'd love to see them put that 707 HP, Supercharged 6.2L V8 into this Grand Cherokee SRT8! I think it would be a great match up with the extra weight and AWD. This truck would be a rocket off the line... Not that it isn't already though ;)
