Upon curiosity, I went over to the Cadillac Europe website to search for dealerships near London.
There was only 1.
From their website showing the relative importance of their brands, Cadillac gets half a line!
"We are also the sole UK authorised dealer for Cadillac Sales, Service and Parts.
Our new range of SsangYong models with prices from only £13,300 for the all-new Tivoli offers the best value for money in the UK car market and every one comes with a full 5 Year Limitless Mileage Warranty.
