I ran out of gas... on the test drive.
I wanted to spend under $30k, so first the wife and I drove a base model. It was SR, which wasn't my first choice but between that and black the red won (I've had a black car before, won't go there again). It was low on gas so they gave me $5 and asked me to put a couple gallons in. I had fun on the drive and liked it of course, liked it a lot.
When I got back I checked out the other Z's they had. They had a Nismo in BS, but that was way out of my budget, so then I looked at the touring model in PG. Liked the color, liked the extra features, so I decided to spend the extra cash and get the touring. I figured I should drive it just to make sure, and I noticed the gas was even lower on this one. They gave me another $5, but I only made it half way to the gas station before it ran out. I called the dealer and they said someone will be right there, it took at least 20 minutes before the pimple-faced lot boy showed up with some gas. I spent the 20 minutes checking out the car inside and out, so it didn't bother me much - my wife OTOH was not amused.
IIRC there was one dot when we ran out. Since then I've gone all the way down to no dots without running out - strange.
