I forgot something I was going to post about the HHR. This was my first out of town drive and I had gone about 100 miles and noticed the gas gauge had hadn't moved. I was thinking wow, this thing really is good on gas. At about 150 miles I was thinking there must be something wrong with the gauge. When a warning light came on I started looking closer and realized I'd been watching the water temp gauge.
So far I like the HHR just fine.
