There ya go making me wish I lived in the UK.....
We get such a poor selection of small cars over here it's sad. BTW what are the details of the cash for clunkers deal over there in the UK? I've found that over here the requirements are so restrictive that so very few vehicles would be both eligible and worth it that I don't think its going to be a big deal.
For example, unless your "clunker" was RATED at 18 MPG or less combined when it was new, it does not qualify. The pretty much excludes just about every "car" on the road and limits the exchange to trucks and SUV's only (even most minivans do not qualify). Then it gets tough to find a truck that is worth less than $4500 since Americans still love their trucks and seem to have no memory of just one year ago when gas was over $4/gallon and people were trying to get rid of their trucks (but no one wanted them). So unless you have a real junker truck (like mine

) its just not worth it. And many people who have a junker truck like that have it because they can't afford anything newer, so they're out too.
Leave it to American bureaucracy to screw up what should be a good program.
