Well if you and your son are petrol heads

Here is some info, I meet up with a relative from Canada in September and we tend to visit a different sort of auto museum, His main reason for visit is for the Beaulieu Autojumble.
Beaulieu is worth a visit for the Motor Museum Abbey and House, all on the one site.

Tank museum at Bovington, South coast.
Haynes Motor Museum ( the book guy )
Stayed at Sparkford Inn, Pub with rooms .
Morgan factory, this was very enjoyable and worth a visit, its about a 3-4 hour run from Heathrow, well worth a visit.

We stayed here and I would recommend it.
http://www.malvern-hills.co.uk/linklodge/index.html Its just up the road from the factory and the owner raced MG,s . There is a pub up the hill that does evening meals.
A few years ago we headed north from Heathrow and visited.
Coventry, here the Coventry transport Museum is excellent, ( as good as the Beaulieu museum)
You can also take a look around the Cathedral if you fancy a bit of culture.
Also in this area is The Heritage Motor Museum at Gaydon, it about a ½ hour from Coventry and of course the Triumph factory is near.
We stayed here .
http://www.badgersmount.co.uk/Around the Heathrow area is the Brooklands Museum, this is worth a visit and there is a nice Mercedes Benz dealer that has a few exhibits’ on show as well next door.
Also be aware that what looks like an 2 hour drive on the map will actualy take half a day.
