Another cash for clunkers question. My mother has a 2003 or 2004 Kia Sedona minivan. The government website says its combined mileage rating is 16 mpg. It's got a lot of miles on it, not in great condition and probably not worth $4500 - trade it in for an efficient small car? [more inside]

A friend has a 10-year old Lexus (with only ~50k miles on it!) that gets driven 2-4 miles per week. Is there any harm in this? (It is a second car for one person.) Oil would keep recirculating due to the weekly drive and the alternator should keep the battery charged. Right? I mean, if the car is fueled only once every 12-18 months can that be good for it? (sediment?) Would any other problems be likely?

Help us pick a car! We're looking for a good used family car. We have two daughters, a 2 1/2 year old and a newborn and need a car that can accommodate an infant car carrier without putting the front passenger's knees in the glovebox. [more inside]

Simple tricks to improve MPG? For instance, I've thought about removing the rear seats/internal molding to lighten my car. I've also thought about aero-improvements, such as moon-disc wheel covers, or even somehow making a cover over my rear wheel wells. I'll be removing my rear wing this weekend, but what other tweaks could I do? [more inside]

Hypothetical-sensible-dream-car-boyzone-filter: After a long phase of big-city living, I may have to drive a lot. I don't want to be a total pig about fuel consumption or emissions. But I want serious performance. Let's say I have $25K . . . . [more inside]
