I've been quite the road warrior for the past few months. The biggest question in my travels is my rental car. I never seem to get the same type of rental car twice in a row. I've run the gamut from a Ford Mustang convertible (and I hated every second of driving that car, which is unfortunate, since I drove it from Portland to Seattle) to a Chevy Trailblazer (which I also hated, because it felt like I was driving a schoolbus).
Aside from complaints about specific vehicles, I've learned a bit about what I want out of my rental car:
These have turned out to be the things that are really important to me when I drive a rental car, and I realised that they're all usability issues. It's just me and my luggage when I travel, so I don't care about making sure I get a big enough car. Assuming that the car has four wheels and air conditioning, I really don't care about the particular car. It's been kinda nifty to drive cars, it's kinda like an extended test drive for cars that I'd never consider buying.
