If you like castles and history with a Dover starting point...
https://www.nationaltrust.org.uk/scotney-castle Is a little way inland but is in my opinion the most beautiful place I have visited in years. Enchanting.
A bit nearer is
http://www.english-heritage.org.uk/...gclid=CPfq8fqSitECFQg6GwodglEKzA&gclsrc=aw.ds Dripping with history, including much from WW2
Turn West from Dover for Brighton (as above from JAWS), the Pavillion is stunning and Brighton is a very cosmopolitan and lively place.
An hour past Past Brighton is Arundel, one of the nicest places for a 'slice of England', stuffed full of history and a stunning castle. Best place I know for loads of good restaurants and coffe shops.

Then head off to the West Country.
There are websites that will help with bed and board, tons of pubs for bed and breakfast, plus coastal towns are also stuffed with b&bs.
Pop in for a bratwurst and stein of beer if you need refreshing.....I am on the coast in Seaford, between Dover and (20 minutes from) Brighton.
I also have a German car:-0)
