Yes no problem once a vehicle is over 40 years old it no longer need to be taxed or have a ministry of transport inspection as its classified as a historic vehicle.
Its also exempt from any emission fines in London
In the first picture is my Mini The challenger produces 275 BHP allegedly the mini produces 96bhp ( dyno tested) and acceleration is pretty much the sane in a drag race. Mini weighs 600 kilos. Challenger sounds better though
i bought my 71 challenger just over a year ago, as with many American cars in UK it was imported by a sergeant in USAF in early 90s, recently fitted Dakota dash and new chrome bumpers.
