fair enuf about the speedo being inaccurate. lol it was down m5 motorway i got it :d. I can't see how a 1.2 Corsa is quicker just can't see it. I no the 0-60 textbook facts but still can't see how a 1.2 twinport can keep up for a 1.25 16v I've had loads of 1.2 twinport corsa race me and they all lose. arh well put it this way lol no 1.2 Corsa will can anywhere near me in me ST I've heard of a speedo being out by a few mph but not 10%. What happens about speed camras if the speedo out? say your speedo's out (by 5mph) if your doin 40 in a 40 and went thur a speed camra it would catch you out for doing 45 wouldn't it but how is that your fault? i dont get it lol
