I have the auto dip and fold mirrors and the auto dj controls which do absolutely nothing in UK but are a nice little extra, keep thinking about selling it to some Americans as they love that stuff.
A stigma about having a jdm car is ridiculous, so what if they are cheaper? They are generally cheaper and better condition with lower milage and less rust, speaking from experience of having over 25 jdm cars they are normally a far far better buy, they actually respect their cars in Japan and properly care for them.
Also with everyone saying get a UK car if the op wants a vert auto then his only choice is a jdm one and there are not in ambundance...
The downsides such as triple gauge and see delimit can be solved cheaply and in about 20 minutes
