I don't drive a flash car. No interest in them, so stick with something functional. Only watch I ever wear is a running watch - my phone tells me the time should I need to know it. No interest in fancy brands.
Clothing wise, I'm probably scruffy, and a bit laid back. I wear trousers, shirt, tie etc. at work, and like to relax in dark jeans, t-shirts, a fleece, trainers etc. when outside work. Will wear shirts if need be.
Don't think I give that "rich man" vibe or come across as what a lot of these girls might be on the lookout for.
I prefer to travel a bit and spend some of my spare cash on that rather than shiny trinkets, something that can do 0-60mph in 3 secs etc......but each to their own.
When I have had successes, most of these things are irrelevant if you're meeting them at your hotel or their place. If you are much the same as your pictures, show her respect, give her a good time, and the allowance is given afterwards, then that's enough for a lot of them.
Surely if you're meeting them in a Premier Inn for £150, she's not going to believe that you're a jet setting multi-millionaire businessman driving a Ferrari, who regularly pops off to Dubai in a private jet and eats only in the fanciest restaurants.....
