Hi Junaid , definitely not a £20k ish car , this is a car for a collector given the condition and the level of restoration and a thread of this can be found in the 60’s section.
There aren’t many 60’s for sale and rarely do they come up in this condition, yes you can import from Japan but you are talking serious money, I would say the car would be in the £30’s but others will be along to tell me otherwise.
