Bought the caddy used in 2007 and put already 20,000 miles on it. No problems so far. Fun to drive on highway and interstate. Gas mileage is quite good. Sometimes I get 26/gal. Uses more oil than any of my other cars. Dealership says it's within normal limits. Doesn't smoke or leaks oil though.
Always more than enough power to pass when needed. The interior is nice and comfy. Quiet and subtle ride.
Rain water drips in trunk when lid is opened. Really annoying.
