The car does not have rear discs. It does not say 83k anywhere on the plate on the passanger door pillar but it does say "entry plus" so I'm still not 100% sure. Just wanted to be sure so my insurance is totally covered.
Cheers for the link, that clears that up. I'm going to go with it being 100bhp as it doesn't have a 83k stamp as mentioned in previous post and it comes up as 100bhp when I enter the reg into the insurance websites.
