I'm not claiming that the other guy (lets call him Dwane, if you like) doesn't benefit from the scheme, my issue is what happens to his hold car.
Pretend you have a 18yr old son, lets call him Dave. He's just passed his test and has saved up a grand of his own money to buy his first car, prior to the scrappage scheme, Dwane's car would now be on a dealer forecourt "part-ex to clear" and Kev's would be for sale privately, on paper they're the same, both have a reasonable amount of tax&MOT left and so on, however Kev looks a bit dodgy so Dave buys the other car. Unfortunately that car, that perfectly good serviceable and not too unsafe car isn't available. So he has to buy Kev's car
This is his first car, the one he is probably going to have a crash in. Now when he does have his crash, that is when he is going to discover that the sills are rusted through and have been replaced with chicken wire and bodyfiller, how is he going to know, because the sills will snap in two and the car will get crumple around him as the sills will be weaker than the crumple zones built into the car (yes they did have crumple zones in 1999).
If Dave is lucky, his new car will fail it's MOT before he has an accident and he will have only figuratively lost an arm and a leg rather than literally.
Meanwhile the only crumpling Dwane's old car will be doing is in a compactor machine.
I realise there will be more than two cars on the market at the time, but all the Dwanes in the country will have scrapped all their good cars and all the Kevs will be offloading them privately onto unsuspecting buyers such as Dave.
But the oldest, least reliable, least safe and most polluting cars will still be there, and will probably be killing someone. This scheme is literally putting lives at risk.
If they wern't forced to scrap perfectly good cars I would have very little issue with the scheme. It's a government bailout just like Obama did only this version actually does help consumers and not just big businesses.
How about instead of scrapping the good cars, the cars find their way into the income support and job centre schemes. If an unemployed person is fully qualified for a job with the exception that they cannot get it as they need to own a car for the job, or to commute to the job, a scheme where they get Dwane's old car for, say, a tenner a week interest free providing they take and keep the job that is offered. If they quit or get dismissed for something that is their fault before the car is paid for then the car is taken back. A similar scheme could work for those on low incomes / income support.
This would be a much better use for those old cars, it might even get Kev's deathtrap off the road if he qualifies for the scheme. Ovbiously this only works for the more mundane cars that come in, the exotics could be auctioned to fund the public purse ie. reducing the overall cost of this scheme to the taxpayer.
But, I hear you say, who decides what the value of what cars are and which are worth preserving, well luckily it's car dealerships who take in the scrap cars and they usually have experienced car salesmen and mechanics on staff. It would be a requirement before the dealer get's it's £1000 of government money that the car be sumbitted with a report detailing the car's mechanical condition, estimated value and suitability for re-use.
Personally I beleive that this isn't happening because the government want to poison the second hand market, they want to get poor people off the road, it'll make the roads look less congested without them having to actually spend any money building new ones or paying for more traffic police to educate middle lane morons.
