I drove a N/A for years on the continent, it does the job but tbh id be looking at least at a 200tdi lump, its better on fuel and far more powerful, will sit all day at 60mph whereas thats thrashing a N/A.
That said, if you're touring round, not in any rush and hoping to avoid motorways/Major routes, a N/A will go on forever.
Personally...200tdi all the way for that mileage and comfort. You'll be deaf and having seizures by the time you get to Dover.
