It sounds good, but I'm not exactly sure who it will help incentivise?
The Govt will give me 2k for my banger.... but only if I buy a brand new car. I'm thinking the 2k will just about cover the depreciation of driving it off the garage forecourt. I drive a 5 door Fiesta. The current Fiesta sells for 10k according to the Ford website. So only 8k to find then!
If I was interested in, and had (very nearly) enough money to buy, a brand new car, then why the heck would I be driving a car that's over 10 years old?
