i suppose the one thing i learned from all my test driving experiences with various makes is, never buy a loaner/test driven car. those things are abused to hell and back.

when i was very young, the salesman would come with me, but now that i have an established relationship with several delears, i can just show up and test the latest model for a few hours without anyone accompanying. when im offered to take home a car for a weekend, i usually decline, if i didn't i would have alot more cars

it all depends on the dealer, there is really no established ettiquette for this.

it is almost expected that you will WRING the car out.

which brings us back to:
