My C Max is 14 years old, cost £4k to me to buy. I've spent probably £500 on it. If it does pop any time within the next 18 months, it will have cost me more per month than that lease deal. Such is the unpredictability of (some) older cars. It could go on for another 10, I just don't know.

Not much different to what keeping my old 14yo Panda for 2 years cost me overall.
