Yet another prospective buyer

Hi, everyone.

I've enjoyed reading the voluminous posts and instructional material at this wonderful site. One question, and then a request for advice:

1. Any thoughts about squeezing a second passenger into the car (curled up in back, I guess) for a short trip? It seems to go against everything I've read here, but I wonder whether anyone has done it. I usually drive alone or with one passenger; this would be strictly for very rare occasions.

2. I looked at, and plan to test-drive, a new 2005 Insight that the dealer said arrived on the lot within the past couple of months. Does that make sense? A trustworthy salesman at my local dealership said it's possible, because of how long it takes from ordering to delivery in this country. I'll check the invoice, of course. Just looking for input.

Thanks!
