Re: Now ask me why ...
... I drive pre-1970 "enhanced restorations".
You don't want to be allowed in Central London anymore when the new pollution measures come in?
I love old cars too (especially the 60s models because they're just mad) but there is no way anything older than approx 10 years is as good environmentally as what is produced today. I suspect even VW will now be OK for a while.
That said, I look at the full picture. Unless we find a better way to produce electricity I don't think electrical cars are the answer either, at present we simply push the pollution elsewhere :(.
