Those prices are real. I
almost nabbed a 2014 ES (higher trim) with 50k miles on it for $6500 last weekend! Alas, someone got there first.
This morning I got a craigslist alert for a 2014 CVT with 10k miles on it for $9k.
The depreciation is pretty bad on these cars, but that is perfect for anyone looking to buy used. There really haven't been any big issues with the Mirages aside from the rear axle assembly sometimes being out of alignment as Old Mech has mentioned.
I'm looking forward to adding one to my stable as soon as I find another good deal.
