I need help finding a large car with good gas mileage please?

It's been really hard for me to be able to find a car thats big enough for me, but at the same time with good gas mileage. I'm 16 years old, 6'3" and about 250lbs. I'm only going to pay $3,000 or less.

I'm looking for a car that has 20mpg or more to the CITY. Any color (would prefer black or white). 4 door. Any car but 2 door, van, or pick-up.

A Mercedes diesel ( cast iron head and block),they will run used vegetable oils.

I got an inch and 50 lbs. on ya and I love my 97 Nissan Maxima. Plenty of room for a big man. You can pick one up in the $3000 - $3500 range and I average 22-25 MPG's. Surprisingly, the only car that I've ever been in that I can't touch the pedals with the seat all the way back is the tiny Honda CRX. Camry's are roomy as well.

Sounds like you can get anything in the wagon or suv styles.

For that price you might be looking at a used ford (sable, taurus, escape), cadillac (pt cruiser) Chevy (aveo, etc.) You could probably get a used Subaru outback as well. I personally think that's a great car. Here's a link that may help you out:
