S3C 6000 mile service

[bena80]

Looked on the Offord website & it looks as though they only cgarge £166 for the 6K service. Since the 12K is 300 odd I am puzzled (though not complaining) about why all other specialists 6 & 12 K services are much closer in price - or are they just charging too much? Anyone else used Offord - I believe they are popular with cambs region members.
