lol I think it would be the best option if something a bit special was in the works. To be honest I land home in something and see if she notices. Most of the time she either doesn't notice or care.
Last year I picked her up from work in the XJ6 and she walked straight past me in it. When she eventually got in she said "oh this is nice - when did you get this?"
Eh about 18 months ago love... it was sat at the house all last summer!!
suppose they all feel the same with a white stick. How she not notice a xj6 lol.
