This vehicle has been a mileage surprise. EPA estimates of 30 are often exceeded on longer trips. A recent 400-mile, one-way trip got 31 mpg with several in town stops, while the return, mostly non-stop trip logged 34.5 on the onboard computer, but 39 mpg when actually running the numbers on the calculator! This was at 59-60 mph for most of the way. This replace a 1994 S-10 Blazer that only did 24 mpg on its best days. I wish professional reviewers would quit putting so much emphasis on a vehicle's ability to rocket off the line. Except for race car drivers, we are not buying cars to win drag races. The HHR has plenty of power to accelerate from stop lights and to merge onto freeways.
Handling. Small size makes it easy to park and maneuver in small places, yet it has a lot of hauling capacity, especially with the rear seats folded flat.
The driver's power seat really should have more ability to go down. That would help visibility when using the visors.
