Yes and no, ours was just over three years old, so just out of warranty, but the damage was our problem. No cover for bloody rodent damage. Our battery was replaced (and the service from our local MB garage excellent) though I will root out the invoice tomorrow to make sure I’m comparing apples with apples.
My friend’s Mini is also a 2017 car and I think the battery is only months out of an eight year warranty, but Mini don’t give a damn.
No, it’s in Dublin. The biggest BMW/Mini dealership. The had the Irish distribution rights for BMW since the fifties/sixties (the rust bucket years before the 2002) and then BMW bought them out (for a lot of money) in 2000 and set up a wholly owned Irish subsidiary. They are historically an arrogant bunch, as one would expect from BMW dealers. In fact , on reflection, any German car dealer in Ireland, including VAG.
I remember looking at a new Golf GTI back in 1980, a mere £6K at the time, and casually asking the salesman if they had any finance deals going (inflation was running at around 17% - significantly above interest rates, new cars were virtually self funding) and he replied that VW buyers (ie the Beetle generation) generally didn’t need finance. Talk about making prospective customer feel small
My bank was delighted to shovel money at me.
A few years ago in a moment of weakness I thought I might buy a Porsche Spyder (a stupid idea, but. well, you can’t take it with you). So I popped down to the local (probably all Ireland, North and South) Porsche dealer.
I was only in town for a few days so hadn’t bothered renting a car and was using my daughter’s (she’d decamped to Oz) little red 2002 Polo 1.4 automatic (a lovely little car we’d had as runabout for her from new). So I pitched up at the Porsche dealership and happily parked outside the showroom in our pet Polo. Well, I was treated with utter contempt 
They didn’t know what they were up against though. I could wallpaper the sitting room with the subsequent letters of apology. Though they did me a favour, I could have wasted a lot of money that day, if they’d been smart enough to take it from me 
I really hate to see these main dealers taking the piss. They treat customers like idiots.
