Is the commercial rate and only if you do not use the jeep for personal use. Your first time taxing it => you will have to prove that you are a company to be able to avail of the cheap €333 road tax. If you can't ... you will have to tax it at the horse power rate NOT based on CO2 emissions. A 2.2 ltr engine will cost you €951 euro or €994 depending on whether it's just under or over the 2.2 ltr.

From the Kerry County Council website: "Commercial vehicles taxed privately are
always taxed on engine cc."

Tipperary County Council lists all you need so that you can tax it commercially:

BUT => if you are going to use it in any private capacity (having jumped through all the hoops for the €333 road tax rate), you HAVE to tax it privately.
If you buy a jeep with a 3.2 ltr engine and end up having to tax it privately, you will end up with a whopping annual road tax bill of €1,809.00
The old system is applied to taxing a commercial vehicle privately => no way around this.

It looks like the Landrover Discovery 4 is a 3.0 ltr vehicle so it will cost you €1494 annually.
As a private individual, you will be hard pushed to prove that you are going to be using a commercial vehicle for commercial work only.
You'll end up getting a bargain but you'll be hit with a big road tax bill annually.
Even if you pay it every 6 months, it will still cost you €829...
Oh.. and because it's a commercial, you will have to DOE it annually... roughly €120 every time you do.
The DOE has to be done on it, regardless of whether it ends up taxed commercially or privately.
(As an aside, I wouldn't touch a Landrover Discovery 4. My brother had a 131 and it gave him no end of trouble. The engine went in it and after a long battle, Landrover paid 90% towards its replacement. It was a known fault apparently. He couldn't wait to get rid of it.)
