Pretty stout engine. I've owned 2 '03 V6's. Weird though, I had to replace cats on both, 1 at 100k miles and 1 at 70k miles. Also the exhaust manifolds are prone to crack (I had to replace 1). Also, if it has the 6-disc CD player, they are prone to jam. Unfortunately I was getting good at disassembly and forcefully ejecting CDs.
