Best 2009-2011 Sedan/Crossover?

My parents are looking for a new or almost new vehicle. My mom wants something bigger than a car, so something like a crossover since there's not many station wagons around anymore or vans to choose from. Right now we have a 2000 Ford Taurus Wagon, it's been a good car, never broken down, but it's needing some repairs that can get costly, especially for a vehicle that's only worth a couple thousand now. We'd like a vehicle that will last a good 5 years without needing any major maintenance (just regular maintenance, ie. oil change, breaks, all fluids etc.). Unfortunately it will mostly be for city driving, but we will be using it to go to Quebec and Winnipeg in the next few months. It has to be a car that's not as high-up as an SUV though because my dad has trouble getting in and out...So as low as a car, but lots of trunk space for a wheel chair (dad has MS) and lots of space for boxes/suitcases/long items etc. I'll take suggestions on sedans as well if the rear seats go down. We'd like the car to come with a block heater since we'll be moving to Winnipeg, an alarm, power trunk/lift gate (preferably), and a gas tank door that can lock. And something that's really good on gas! We don't have a preference exactly as to what make, but it needs to have an automatic transmission, be under around $27,000 (CDN), and comfortably seat 3 people, so just give me some suggestions on some good reliable cars, thanks!!
