From past (and ongoing!) experience, My long suffering wife would probably say.... Middle aged men in.....
"lady cars" , Mx5, Fiat/mini convertible or similar... Especially the go fast versions in bright colours...
Cheap/low powered Merc convertibles (some are 1.8 ffs!)....
Yooofs cars....go fast astra/corsa etc.... Especially​ old and cheaply modified ones...
Wannabees....expensive, fairly new Evo or Subaru...anything with big wings on the back really...which also excludes some really really tasty machines such as ...Lambo, Ferrari etc!
All motor bikes, no exceptions....
....and that included my scooter​!
The above needs to be considered in the context that she would rather I took the GTi badges off my Eddy. Otherwise it's acceptable, but only just.
...a new mk 7R has a silly exhaust, and a Focus RS is not acceptable... I asked!
Opposites to the above? Acceptable as not a mid life crisis, just a show of wealth/success?
"Normal" Aston Martin, Jag XK/XF, 911 etc however see above re wings!...and very colour dependant.
However....it depends on your target audience. if i was in the market for a new Aston, I very much doubt that I would be at all concerned about the opinions of a middle aged teacher, or her friends.....
