Cadillac CT4 Makes Unofficial Debut In New Spy Shots
Most Cadillac buyers and leasers are not worried about performance, as they drive for comfort and quietness. A heavier CUV actually gives more confidence to the driver and passengers, and promote better and longer useful life. My wife's 2009 Chevy Equinox may be heavier and slower than the imports but it is safer (five stars) and had an almost perfect service.
I am waiting for a hybrid or EV Cadillac before trading in.
