Actually as long as none of it extends past the sides or rear of the car and it's properly attached it would be legal. It looks OK to me from that picture. You would of course have to tell your insurance company and they may have a different view of it.
But I think over height might be a problem.
<SNIP>
Edit, that clearance used to be 11 foot, 8 inches and was raised to 12 foot, 4 inches and still gets whacked.
Exactly that, the height alone would make it a liability and a guaranteed magnet for any law enforcement officer
I don't know, scaling off the image it looks to be about twich the hight of the car. The XJ is 1.3m high. So dragon is 2.6m. That would be about 4m /13ft total. In the UK that would not make it a tall vehicle. The standard for tall is >4.5m. Standard road clearance in UK is 5m / 16ft.
The biggest issue I can see is stability. The raised CofG could cause issues bu it does not look that heavy.
I don't think it's the CoG that you'd need to worry about, it's the CoP. That and the lift. Do more than 15 mph in that, hit the wrong gust of wind as well and I reckon that you'd be doing somersaults.
IIRC back in the 80s the Ford Sierra's CoG and CoP weren't in the same place. Apparently a stiff crosswind meant steering was less precise than desirable.
That is correct, I remember someone famous having a crash in a one when a gust of wind caused it to swerve violently. I know that they did not like water, I hit a patch of water on the road and spun a new hire car round and got shunted through a hedge, wrote the car off. Thing is that I had hired a different car for the following day as the 2 cars I had booked were going to become the new company cars so while my old one was being serviced, I thought I'd try them out. The hire company refused to let me have the other car, I wonder why
Drifting a bit off topic, but, again, back in '72, I hired a Mini in Ireland, which left me a bit "thin on" for funds.
One cold, but sunny morning, as I crested a hill, I noticed a fuel tanker coming the other way, that seemed to be spinning its wheels.
Being a cautious driver, I braked---not a good idea!
That was my introduction to "black ice"!
Whilst the Mini was performing several rotations, I was imagining explaining to the hire company how I had wiped out their nice new car, & having to fork out money I didn't have for repairs "not covered by the insurance", but luckily, the slushy, muddy crap at the side of the road had enough drag to stop the Morris' acrobatics, so I drove on, much chastened!
