Ooh, love those wheels - used to have a set of those on my old Corrado G60. Make sure you get good quality adapters though - Two of the bolt holes are very close to each other (due to the 4 to 5 stud pattern) and have heard ofcheap onesfailing! I think I used H&R adapters, not cheap but top quality.
£70 sounds a bargain!
Teledials are worth little these days. £70 without tyres and needing a refurb sounds about right.
You need to find out which model they are though. Pre-ABS cars had a 23mm offset, and there is no way you'll be able to fit them to an up! Post-ABS cars had a 52mm offset, which with a 20 or 25mm adaptor will sit very nicely on an up!
FK Adaptors are around £100/pr and widely used by the modifying crowd.
