By using Google maps, I can figure out not just how to get from point A to point B, but also the number of miles and approximate time it would take to get from A to B. Is there a map that will also let me approximate gallons of gas? [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?

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]

Last night on ABC news there was a guy with a VW beetle (silver) who put a wicked-huge wing on the back and claimed some ridiculously-high MPG figure. Alas, my google fu fails me. Why would this wing possibly work? They guy wasn't a tuner, AFAICT.

I just inherited a 1998 Mountaineer that has only 20,000 miles. It's never been tuned up and still has the original tires. I'm pretty sure the spark plugs are fouled because it's never been driven at highway speeds. Everything appears to be in great shape. What kind of problems can I expect from this car? [more inside]
