I've been very happy with the Camry. Not sure if you're looking new or used, but you can find Camrys in great shape with low miles in the $12k range.
My 2012 LE with the 2.5 gets phenomenal mileage; I get about 40 mpg at 70 mph. (It's rated 35 hwy.) I've had a number of tanks at 39+ mpg (hand-calculated). My lifetime average is about 31.5 mpg, including a fair bit of severe winter driving and city driving. It has a composed, comfortable and quiet ride and is surprisingly feature-dense. The backseat and trunk are surprisingly spacious. I'd recommend the Camry hands-down, though I do like Accords as well. I've driven it 500+ miles at a pop and it's been quite comfortable. I've spent some time in your gen Civic and the Camry seems to be a big upgrade in space/ride comfort for a minimal price/mpg penalty.
The other Toyota in the family, my mom's 2010 Sienna, has been darned near flawless. Its total repair bills are sub-$1000 for 205k miles. It has no rust to speak of and has been a true pleasure to own (no fluid changes other than oil changes, no belts or hoses, no suspension parts whatsoever (no tie rods, shocks, control arms, etc., nothing!) It feels quite young at its current mileage; everything works as designed. Nothing's peeling or cracked, even with being a family vehicle (plus a dog) for 10+ years. Essentially all that it's needed are oil changes every 7-10k, tires, brakes, a VVT oil control valve, its only failure ($450 at the dealer), and two batteries. Oh, and two light bulbs. It still looks great, despite what it's been through. I couldn't ask for better service!
