Many dealers are just stocking and installing Interstate's now. Mine was just done, $504

 

I have a group 47 case LTO battery in my 06 Vantage when the original was a group 49. I tossed the group 49 into my parents' Pcar to replace the old group 47 lead acid battery. Based on that experience, I assume most European cars have a tray with mounting holes or clamps that will fit 47, 48, or 49.

14k sounds pretty crazy but I guess I've seen a lot of random shops in California asking over 240/hour labor and with AM parts markup it doesn't take much to get shafted.

 

Which battery did you end up choosing? I am thinking about replacing mine too...
Thanks!

 

The factory Interstate battery since the dealership stocks them.

 

Would be very surprised if rotors need replacing on these cars before 50-70k miles unless you are tracking it. If the car brakes smooth and rotor is within thickness measure (buy w micrometer on eBay for $60) then they are fine. I have 16k miles and 60 track days and my oem Shelby gt350r rear rotors are only half worn and brake smooth. I replaced the fronts after 40 or so track days only to large cracks starting around the drilled holes (and to switch to the new solid design without the holes). Our cayenne gts made it to 82k miles on oem pads and rotors are just fine, did a cheap diy pad slap for a few hundred and they are probably bigger brakes than on the Aston.

also, learn to diy pad slaps (and rotors) and get a $100 motive brake fluid bleeder. Watch a YouTube video or two and this will save 10’s of thousands in brake related labor for your lifetime of car ownership. They call them stealerships for a reason.
