The Leon Cupra that I bought in 2002 had 235 miles on it. The dealer had to collect it from the other end of the country as I was going to the South of France the next day. That car had 2300 miles on it in just over a week.
Dubber, how did you find running it in on such an extended run? Not supposed to be good running the engine in at constant (motorway) speeds.
Was the Cupra ever compromised as a result? Be interested to know.
I can't say it did it any harm at all. I had it for 3 years and over 60,000 miles without a hitch. It never even used a drop of oil between services.
It did get a few squirts to vary the speeds along the Auto Route. Despite nudging 100mph at times, it was only ever done on half throttle on the way down. Coming home, it did and indicated 145mph, which obviously was full throttle, but it had done nearly 2000 miles by then.
I think that there is a lot of un-necessary concern about the way to run a new car in. They are mass produced consumer goods, that are over engineered to take a lot of abuse under wildly varying conditions. I'm not suggesting that they should be abused, but common sense and a certain amount of mechanical sympathy is all that is required.
