Car is running great, covered just over 1000 miles. Not run in yet, getting 35+ MPG round town and 46+ MPG on a longer drive. Cleaning today, topped up windscreen wash and noted engine coolant expansion tank was AT minimum level. From what I've been able to gather, this is normal with a cold engine? Radiator cap removal revealed a full radiator, but was a little confused with expansion tank level being so low? Will check further with dealer but expect level to rise in expansion tank with hot engine. Guess will know more tomorrow, just about to tow for a hundred mile or so. Update soon.
