Most of the clunkers weren't going to go 126,000 miles so how is it that the $4500 subsidy broke even in terms of gasoline price savings? And then the government lost money because they were getting less fuel tax receipts. On top of that, the vehicles destroyed had real value.
The people who took advantage of the program were eventually going to buy replacement vehicles anyway, so they purchased earlier than they would have otherwise. So there will be a downturn in sales.
On top of that, accorting to Edmunds, the average of profit for the dealerships went up from $1200 to $1700 for the Ford Escape and $700 to $1500 for minivans. So the people who weren't in the 'cash for clunkers' program paid too much.

OK, so explain the social utility of the $3 billion that was spent. I can't make the figures work out.
If we assume that $4500 is a good proxy for the lost productive value of each of these destroyed assets, then how much reduced maintenance and fuel is needed to make this value-neutral on a cost-benefit test (ignoring any value from the multiplier effects of the primary (stimulative) purpose of the program)? On gas alone, we'd need to save 1800 gallons at $2.50 per gallon (assuming none of the oil burning externalities which are the secondary point of the program). If we get an average 25% fuel economy improvement (say from 14 to 17.5mpg), it takes 126,000 miles (~10 years) to payback in simple fuel savings. Well, that probably is more miles/years than most of these vehicles have left before they'd have been scrapped anyway. I'd guess half of that is a bit more reasonable average. But it isn't hard to see maintenance reductions saving half the $4500 dollars over a presumed 5 year additional life of the junked vehicle. If we saved just $450 bucks a year on maintenance of a 0-5 y.o. vehicle over a 10-15 year old vehicle, I'd say we broke even (given that the gubbmnt cost of money's about zero, and especially given that they own a big chunk of the mfg's).
Now, I'm definitely not claiming the buyer is saving money over this timeframe, but the consumption of new car would have happened even if we'd allowed the trade-in to be sold. So really, all we are doing is moving future consumption of consumables like gas, tires and car parts up from being distributed over the next five years into the present.
