In 8 months and 2000 miles nothing has stopped the car from driving. Have had some strange noises and 2 oil changes - one at 200 miles - one at 900 miles. Changed filter only for the 900 mile change and used a cheaper oil for the first change since the oil wasn't in for long and car was running-in.
I bought some inner tubes. You'll need a jack to change a wheel but I did manage to get the front wheels off without removing the mudguards but it isn't easy and requires a good deal of fiddling and upward pressure on the mudguard as you try to push the wheel on. Best not attempted first time by road-side!
Car well bolted in general but spanners and other suggestions very sensible.
I would generally avoid a long run without a period of time to sort out any oddities or slight adjustments needed, but the latest cars seem fairly well sorted. Good luck!!
