Anyone know this car? Azure Blue B5

[RS2_Russ]

Hi guys,
Looking at buying this Azure Blue RS4:

http://www.nickjohnsonmotorco.co.uk/use ... 7363184447

Reg is X943 BGX. I am asking to have it restored to standard (from 450), except for the H&Rs.

Anyone know this car's history? Anything to be wary of?

Also, is the MRC re-map detectable? Insurance is +50% if I declare it as chipped.....

Thanks a lot,

Russ
