Family Size Cars?

[Supergas990]

We've had a 2003 LeSabre for 9 years and 160,000 miles and it got smacked in the rear last week. Since then I've been scouring the internet looking for a viable car candidate to replace it.

Unfortunately, it appears there are few companies that make a full size family sedan (will seat 5 comfortably). On a road trip (2-4 hour drive), I'd like to get more than 20mpg and have trunk space, etc...

My kids are 11, 9 and 5, and will continue growing. So what are my options? I loath Mini-vans and thus far have been able to avoid getting one. Am I out of options? I'm looking for something used.

I really love our Buick and the GM 3.8 engine, as I've been doing all the maintenance on it and know it inside and out.

Help is appreciated.
