Have driven from Wirral to near Hannover in 2 days, three times.........an absolute breeze in a quality motor car.
Have driven from Wirral to Andalucia in 4 days in an old Merc twice each year for the past 12 years...... again an absolute breeze.
The secret is to select a quality vehicle, take your time, enjoy the scenery and listen to the wind!!
