Gentlemen, I wish to borrow from your collective expertise. Been considering purchasing a luxury car, something not too terribly pricey. Local Chevrolet/Cadillac/GMC dealer has 3 used Cadillac DTS' sitting on their used car lot. I like these car's but also scared to death of the Cadillac Northstar engine's. I would much appreciate your thought's on these good, bad, or indifferent. I have a strong hunch that a Toyota Avalon or a Lexus might be a much better choice.
