Our last car was a 2007 Fiesta and was outside day and night, we live in Yorkshire, and never failed to start first time. So am puzzled by you changing your battery on a 2 year old vehicle.
I like Fresh cut rose and True rose but not the candles as all I can smell is paraffin. I use them in cupboards and drawers or I use the reed diffusers.
M&S have some nice necklaces for less than £20. I also liked a hard wire necklace that had an understated glitter covering it in Boots sale for £3.00 and it has an extender and looks lovely. OK might not look good for long but not too bothered.
