First time I encountered Stop/Start was in a hire car on holiday in Italy.
When it's 30 degrees, you're in a traffic jam and the car suddenly just stops running it's a bit awkward and causes more than a little panic! It gets worse 'cus the air con goes off
. Don't like it at all as I tend to keep cars for many years and can't get the wear and tear on starter motors/batteries etc. out of my mind.
I've had nothing but good service/price from Tayna having been put on to them from folks on here.
I'm guessing they don't have an option for the 5 year warranty as you're asking the question. Maybe give them a call?
Bosch & Varta seem to be reliable choices. Had lots of Yuasa on bikes and they were decent until replaced with a Odyssey which was awesome but pricey.
Good luck with the search.
Andy.
PS. Saw this a few days ago - might be a help?
