We have almost 100K miles on the 5 -- purchased with 42K in 2011, and we have put almost 20K a year on it since.
It's been reliable and economical to operate, and adequate for our family of 5 (including 3 young girls).
A little tight for the several road trips we have taken (several times to
Chicago, Connecticut and Florida), but a rooftop box solves the space problem. Fuel economy ranges from 23 in town to 30 on the highway (driving at 70 without cargo box.)
Overall average of 25 mpg, usually with 3 kids inside.
Completely reliable since we have owned it. Economical and smooth to operate, with an agile feel while driving. Sliding doors are light enough for our girls to operate most of the time.
Great visibility out the front. Strong lighting from headlights.
Good looking when it is clean -- the LED taillights, low-profile wheels and tires, and overall lines look more sophisticated than your typical crossover/family truckster.
If you are wide of girth, this isn't the car for you.
I'm comfortable (I am 5'10" and 175 lbs), but larger folks will notice that the seats are small.
We have encountered some of the groaning suspension noises, but independent mechanic can't find a problem -- the noises are just an occasional nuisance.
Power is modest on the highway, though the engine is smooth. Stability control only became standard in 2010 -- not available before -- the 2010 models are the one to have. OEM tires should be better quality -- the replacement Continental DWS tires that I installed were much more refined and durable. I would have loved a diesel option for better fuel economy.
