Debating financing this Ford fiesta zetec 1.25

I’m currently debating financing a 1.25 2013 Ford fiesta zetec. The selling price is £7.3k, it has 15k miles, full service history, parking sensors, warranty etc. The dealership itself has very good reviews it seems so everything seems very positive. I’m looking for a decent car to keep for 3-4 years minimum.

My main question lies with, should I be concerned about the such low mileage? And do you think 7.3k is a high price for a car like this (rising to around 8.5k over time), taking insurance into account as I’m still a relatively new driver.
