...says the car rental lady.
Well, yes, I believe I've heard that little joke before, but it's a product YOUR company offers. Are you telling me it's inferior?
That's like walking into an apparel store and the clerk saying, "Oh, you're not buying those pants are you? 'Cause they're really poor quality."
She was trying to convince us to take a foreign economy car. We had already planned on getting the Ford Focus because that's what we had reserved online, so when she asked us if the other car would be OK, we protested slightly. By that point in the process, we had become a little suspicious of everything she said. So we held our ground and requested the Focus.
OK, she said, and then dramatically pointed out the company's free roadside assistance number "just in case you need it."
So, that was how we got our very first rental car. We were very pleased to find an almost-new Focus awaiting us. For us, that was pretty special -- any nearly new car of any make is very cool.

I admit we put the car through some severe conditions -- dust, extreme heat, severe inclines, etc. And it held up just fine. The car handled well, was comfortable, and over all FELT very much like my four-year old foreign car. It had about the same amount of room in the interior and trunk and comparable features.
There was, however, one very big difference that quickly became apparent:
GAS MILEAGEOK, my four-year old Japanese car gets about 37 mpg highway, sometimes even more than that. The 2007 model of my car gets 40 mpg highway.
The brand new Ford Focus?
27 mpg.
That difference adds up fast, especially with gas prices ranging between $3 and $4 per gallon.
So, Ford can build a car that feels and looks about like my Japanese car, has about the same amount of interior space, and similar features, but it can't make that car get comparable gas mileage. This wasn't, of course, the first time I'd realized this issue with American cars; it was just the first time I'd experienced it for myself as a driver. To be honest, it was depressing.
6/26/07 Update: According to various websites, the mileage for the Ford Focus ranges from 27 in the city to 37 on the highway for manual transmission (we were driving an automatic). Soooo, take the above as what it is: a random anecdote from a short-term Ford Focus driver.
