Fair enough point, those cars are rock solid.
My point is that given the same difference, a different car
may output a LOT less hydrocarbons (wanna borrow my car?

1.4 litre remember). A different car, chosen wisely, cirtainly doesnt mean a more dangerous car.
Just wondering (I'm not being arsy here, i really DONT know) do those Lincolns have airbags? Side impact protection bars?
Anyway I think we have a duty to be responsible in the way we treat this place. (Take no notice of me, I must be disgruntled with society

)
Edit: It may pass emissions tests, but that doesnt in anyway mean you are being responsible with the use of that car. The US govt. doesnt agree to follow emissions reduction policies set by other countries anyway...
