Hi Jay,

Well, that's pretty much all you'll ever see at a taxi rank in Berlin or Munich so draw your own conclusions. Just watch the 2002 - 2010 E-Class like a hawk. They were pretty shoddily built my Merc standards and developed a lot of electrical, braking and transmission problems.

Hi Alan,

Electric Ireland charges a standard 19.28 cent per kWh as of Jan 20th 2014, according to moneyguideireland.ie. Other suppliers charge more or less the same although there can be a variation of up to 3c per kWh. 

In terms of what is charged to charge an electric car, the energy companies make no distinction. The plug points are downstream of your electricity meter so it's counted as the same juice that goes into your fridge, dishwasher or vacuum cleaner.

The total amount of tax charged on your kWh amounts to about 11 per cent, including both VAT and Carbon Tax, according to Sustainable Energy Ireland. 

So, why is this so much lower in tax terms than the 50-odd per cent levied by various charges on pump fuel? Simple: expediency. On the one hand, the Government must be seen to be encouraging the use and development of electric motoring. On the other, there is currently no simple and reliable way to distinguish between electricity being pumped into your car's batteries and what's being used to light, heat and wash.

That said, you can sadly and safely expect that to change, rapidly, if electric car sales ever take off in a big way. The Government has been very careful and canny about making sure that improving vehicle economy hasn't eroded it's annual €1 billion+ tax take from petrol and diesel sales, so if battery cars start eating significantly into that, expect some form of battery levy or electron tax to be enabled tout suite.

Hi Ambrose,

Yup, that figure is correct. There was a model year change in 2012 that saw the emissions of the 2.0-litre D-4D diesel engine fall from 135g/km (Band B2) to 120g/km (Band A4). Mind you, the difference in annual motor tax is only €80 so it's not a huge thing. There were some other minor tweaks in terms of equipment between the 2010 model year and the 2012 version, but nothing major - the core of the car is still the same and for the sake of that €80 gap in the tax bill, you may well be able to argue yourself a better deal on the older model.

Hope that helps

Hi Louie,

It depends which Stream you mean. If you mean the Stream sold here in Ireland between 2001 and 2005, then you’re looking at €544 a year. If it’s a more recent Japanese import model then you’ll have to get the CO₂ figure for the specific model that you’re looking at, but as far as I am aware they hover around the 150g/km of CO₂ mark, so will cost €390 a year to tax.

Hi Vittorio,

Oooh. Aargh. Ummm. God, this is actually a real toughie as I utterly adore both cars and they're both ideal picks. 

OK, I'll lay out the pros and cons and you'll have to make your own mind up from there.

The Octavia will likely prove to be the more reliable in the long term and is much more spacious and practical than the Beemer. The 320d, by contrast, is much sweeter to drive thanks to all the usual BMW rear-drive balance and it does have a nicer interior. 

To be honest though, I'd grab either with both hands and not let go. See which one you can find that's in better condition or is better value.

Let us know what you decide

Hi David,

That's a little strange. The only tax band that costs €330 per year is the 1,101- to 1,200cc range for pre-2008 cars. Could your car have been classified incorrectly?

Hi Helen,

The automatic version of the all-wheel drive Outlander has higher emissions than the manual one so it costs more to tax - €390 versus €280 per year.

Hi there,

There were two slightly differing versions of the first generation pro_cee'd 1.6 petrol when it comes to CO₂ emissions. The version running on 16-inch alloy wheels records 145g/km, while the one on 17-inch wheels emits 148g/km. It makes no major difference, as both will fall into Band C for motor tax, with an annual bill of €390. In terms of fuel economy, there's also a slight difference, with the 16-inch wheel version doing a claimed 46mpg, while the 17-inch one is slightly worse off at 44mpg. Resale values for these cars seem to be holding up quite well, with asking prices for a 2011 model hovering between €11,000 and €14,000.

Hope that helps

Hi David,

No, but the previous owner will be liable and will have to pay the back tax and a penalty.

Hi Brian,

Well, when you say 'super car' that would suggest that money is no object so...

Your choice is slightly limited as there aren't yet any full-on mid-engined diesel supercars, but there are three German powerhouses in the shape of the BMW 640d Gran Coupé, the Audi A7 3.0 TDI Bi-Turbo and the Porsche Panamera Diesel. (There's also the new Maserati Quattroporte diesel, but it pales in the power and torque race a bit.)

Of those the BMW is the best - frugal and well under the 225g/km limit but damn near as quick point to point as an M5. 

If budget is an issue, just grab yourself an E60 BMW 535d. Wheelspin in third gear in that one...
