I agree with getting some diesels in there (especially for Europe) but I think once you grow a brand too fast or too big, it waters down then entire range. With only a handful of cars to take care of, Cadillac has been really rolling out some good cars, but if they keep adding models in every class, it won't be too long before it takes 7-8 years for redesigns which means all of your competitors are always a step ahead. Look at Acura. They used to make some class leading cars and now they have as many models as Honda and they've been sucking lemons like Lincoln for the better part of 5 or more years.
