There is surely a greater overall impact on the environment in scrapping and manufacturing new "eco" cars than continuing to run older cars. Especially for those doing low yearly mileage. If the goal is penalising pollution, then the only fair way to do that is replace motor/road tax with more tax on fuel.
No motor-tax here in France which is great for me for now
Looking forward to moving back to Ireland in a couple months...not. Motor tax on the KV6 would be a whopping 1080€ (2497cc). Madness.
The way I look at it, it's the last chance now to run old-school nasp, gas guzzling, fun cars before we're all taxed to the scrap yard and into euro-minis
