In my ears of driving quite a few cars have gone to the scrap yard also.. My car before i joined the scheme back in 2011 was on 120k and was on a 51 plate. Sometime’s it’s just not worth fixing them due to it costing more than it’s worth.
Another thingi forgot to mention is that you can extend the lease after 3 years.
All one has to say is you cannot find anything suitable or afford the newest versions AP. Especailly in your case where you paying quite abit. Then you can keep it for 5 years.
