I owned a 20 year old Pajero, commuted with it daily and it cost me less than 250 a month maintenance. Probably closer to 80pm for maintenace if it'd to roughly divide it up in my head but I did have a lot of crap to replace on it at one point.
Though it seems owning a 1 series over 3 years, you'll lose about £7k so if the full cost of PCP is £11k over 3 years then you'll lose roughly £4k? But you'll get a brand new car rather than a 2nd hand and of course servicing bills. Examples are a 2019 v 2016 118 m sport.

Assuming 7k miles a year, this seems (roughly) right?
Yeh this is where my head has been at.
PCP to me doesn't seem that great because most people treat it like PCH (they hand the car back) except the monthly tends to be higher.
I guess the saving grace is if PCP works out, you have a deposit ready for the next one (but equally you could save the difference to do that).
