I shouldnt be too worried about the low mileage. Mine is March 08 and i have only done 15500m miles. When i bought it i expected to be doing that each year but situations, job etc change
, i am also lucky enough to have an MR2 as a second car and i tend to switch between the 2 in the summer, never leaving the FR for more than a couple of weeks without using it.
As has been said service history is important even with low miles, although my mileage is nothing i am having the CAMBELT water pump etc changed next week as its 4 years old, that and the Service and MOT £600
Have a test drive you will love it, i still love mine everytime i drive it.
Good luck with it and Crono is a great colour IMO for the Leon
