"£2500, £3500+ if I do everything I want to. I love the car, and it's done me well, but there's still some common failures that Haven't happened yet, so need to budget for them in the near future, that's another £600+"
It's a lot of money. However, what would another car cost you? I'm 99% sure that a Jag XE would cost you more to maintain. Also you say, "the things you want to do". Why not concentrate on the must do first? If all goes well, work through to the wants. I defected to Jags 2 years ago and spent a fortune in addition to the purchase price. I'm hoping that my disel Connie will now last me until I hang up my gloves, (or boots).
