ignore the time, look at the miles.

motorway goes right near rochdale and coventry so you could technically time it from motorway on ramp to motorway offramp, but thats no less than 120miles using the M5 toll.

he would need to slow to a stop for the M5 toll too, so even if the motrway was properly dead he wopuld need to be consistantly properly going some for the entire rest of the way.

id say you could do that in a Astra VXR fairly easy, obv it jus means you need to average 120mph, but itd have to be a dead quiet night just so he wouldnt have to slow for much.
