I took my dog with me when we went test driving for our first new car.
If he didn't fit happily, I didn't consider the car. The dealerships were surprisingly cool about it. Guess I wasn't the first to bring something along that just *had* to fit in the new car.
(ended up getting Subaru #3... had a 1986, a 1996, and my first brand new car a 2005) My Imp holds one bike in the back with the seat down and the front wheel off. I suppose I could stack one bike on top of another, but I have a Thule rack for when I want to carry more than one.
