Wow, did a little rummaging around, the Alfa, BMW and Nissan are all over £300 per year to tax.
Mini Cooper convertible comes in at £145 if you pick the right one.
There is some reason behind the figures.
I have a small side job one week per year that earns me roughly £1000 and that pays for the upkeep of my toys, Morgan tax and insurance is around £600 per year, I expect insurance will be around £250 leaving just £150 to tax whatever I get.
More hairdresser then MX5?
