If like your a frequent visitor to Autotrader (im addicted!), looking at all the cars you would love to buy, I came across ths extension called Auto MOT, you add it to Edge or chrome and it scans the ads photos for the reg number and if it finds it, it will then automatically pull up the MOT history details etc. I know you can get this direct by going on the gov web site, but this extension saves you the bother and makes it a useful addtion to the the advert info - enjoy
