With gas expected to break through $55US a barrel permanently and
possibly even $100US within the next few years, I'm seriously
considering flipping my car to either natural gas or better yet,
e-power.

Anyone know of websites that deal with what it takes to convert a
Volvo off of liquid hyrdocarbons?

I know that some will say "why convert the 850?" and I agree, but I'm
driving that currently and most of the V40's in the wrecker yards are
usually crunched.
