Drove 1200 miles in a cavalier 2.0 sri 16v in a day that was with two kids the wife and two weeks worth of luggage and quilts etc, I would much rather do 1600 miles in my TVR in a day
16 hours for 1600 miles, they said its too easy. 12 or 13 is more like it. They gonna be in germany for part of it too so the autobahns will make up some time.
Used to do Glasgow to Pisa in a day in my previous car but haven't tried it in the cerb yet. Soon possibly, got to build up my bank balance for all the petrol tokens first though.
