Ok ... so collected the car today ... checked the air filter, which was new (and easy) and checked the oil on the dash gizmo ... all ok so assume that the service promised had been done ... maybe I shouldn't be so sceptical.
Very happy now having driven it some 60 miles on both country roads and motorway ... only criticism would be about road noise from the run-flats, awful on the M27 which is mostly concrete slabs or something - lousy surface anyway, but fine on good smooth asphalt. Are ordinary non run-flats noisy? They're pretty fat tyres so maybe they are. Also the ride not as harsh as I'd expected, even with the run-flats. Glad I chose an si SE though ... I can only wonder about the ride quality of a Sport or an M ... have your fillings out in a flash! Had a job to find one as nearly everything on the market was a sport and I could only find one si SE at the right mileage and price (for me!) ... Hadn't realised that it's got an M steering wheel ... knew about the sequential box with the lever and the flappy paddles ... looking forward to playing with those. Best feature - bags of effortless grunt. Worst feature - 3 of the wheels have got a little corrosion on the inside of the rims, couple of inches wide, which I'd missed before ... I'd thought it was dirt in there and instructed the garage to clean them ... one of them is fine ... suppose it will be a trip to the ally wheel refurb man! All in all though - very happy! I can feel a trip to the South of France coming on already!
