An hour from Liphook to Heathrow with no traffic. A3 around Guildford is a bit of a pig at rush hour, though you will probably be going against most of the traffic. M25 though is another matter.the later you leave the quicker the journey, so if you could get a late flight you should be ok. Probably some on here that use the M25 will be able to advise more, but it alwys seems to be down to 40 mph when I use it, which basically means it is at a stand still.
an hour!! In a Sinclair C5!
