£1K back in 1981 is the equivalent of £20K now Brian.....you wos robbed!!!!
But seriously, £1K then is worth about £5/6K now.......am sure similar applies to the B20s...so the values have gone up quite a bit. Its more the time effort and grief it would take to research, find, pay for ( premium too) and then ship same to UK....factor those in and its 20/30% of value of car, so you must add that in to "value" of car
