They make special cheap interiors, use different engines, or tire pressure sensors for the Lowes/Home Depot fleet vehicles?
I used to work in the car rental industry. I can assure you that it is an excellent way to judge the quality of a vehicle. Of course, that was back in the late 80s to early 90s when American cars were by and large complete garbage. Let me put it to you this way, we would get in a fleet of new vehicles, GM, Toyota, Ford, Buick, Dodge/Chrysler, send them all out into the world and then 2 years and 30-40,000 miles later the ones that held up the best were the Toyotas. Ford wasn't bad, Dodge/Chrysler interiors held up well but everything else was failing. GM and Buick were falling apart and constantly in and out of the dealership. I had a brand new Pontiac with less than 100 miles on it just quit running on the freeway at 10PM on a Saturday night. I could bore you for hours with tales from my car rental days.
BTW-I rented a Ford Escape a few years ago and put 300 miles on it in a weekend and I have to say I was impressed by it. Nothing to complain about anyway...well, other than the gas mileage.
How do you judge a vehicle? By a 15 minute test drive at the dealership? Consumer reports?
