Dumping stock and the £ at it's best rate against $ for many years, would seem good value to buy boat later this year ... make the import costs worthwhile.
Don't think this is general decline in US though .... I work for a US company and we have just posted our best ever figures, expanding & recruiting ... so it's not all doom & gloom.
Personally (as was mentioned by others) the US has had, and still does have it far too easy on fuel .. resulting in large inefficient engines ... I was in Florida, had a minivan with a 5.4L engine and this had less go in it than my Honda Civic !
Good old U S of A has enormous resources, if the car industry had to put the effort into producing engines that made less emissions & greater fuel economy to match what most of the rest of the Western World has to do .... the improvement would be catastrophic.
Market forces are one thing ... but it is cost to the pocket & legislation that makes things happen.
I have a petrol car that averages 42 miles to the gallon, I chose that car because I wanted a quality but cheap to run car ... and manufacturers have produced cars specifically as a result.
They know that quoted urban cycle MPG figures affect the choice of car that many people make ... so they make more efficient cars.
Just be great if US came on board with this philosophy, and the big car manufactures really put in the effort .... this would have a great knock on for boating.
Me .. I would rather see the money spent on improving the world we have than sending multi trillion dollar space shots off .... I don't really care what is in trail of some distant comet, or what the surface of Mars looks like.
