We will be renting a car to drive from London to Holsworthy via Exeter.
We have never been to this part of Britain before. As I request a route via the AA I get either the M3 in the southern part or the M4 via the northern part (via Bristol area). Which one would you choose?? It is not that important if the best route is half an hour or so longer. As tourists it will be best if we drive across memorable landscape. Which one would you choose and why?? Thank you.
