My Dad's owned 2 Cadillac's in the past & they were really sweet rides. Personally I considered several different Luxury brands.....Infiniti, Cadillac, Audi & Benz (I've driven several BMW's in my time & could never figure what all the hype was about with them.....they didn't even appear on my radar when I was shopping)......a few professionaly mechanics have told me pretty much the same thing of all but the Infiniti.....unless the Caddy, Audi & Benz have a long time to go on the warranty.....you better stash some considerable cash away when (not IF) problems start to happen.
Drove Infiniti's & for about 8 seconds I considered Acura as well.......as of today......I am on my second Lexus ES.....nuff said. :D
