who said anything about relationships? this is only about getting laid.
And if you are loaded and want to avoid gold diggers, nothing is stopping you from going 007 on it, rent an apartment, buy a beater, and pretend to be broke
What do you define as decent? If you want the vroom vroom get a cheap-ish sports car like the 350Z ($30K-range), which while being a bit high profile, is still low enough to ward off the gold diggers.
If you go higher into luxury sport car territory... that's your own fault :)
if you think a 30K car will ward off gold diggers you are way off. 20-25K is the most you can spend, and even then that accounts if you are buying new, if you buy a used M3 all bets are off.
How on Hacker News did we get into talking about which sports car will get you laid but still ward off gold diggers? There are at least three things there that, no offense because I'm including myself, this would be the last place I'd look for advice on.
I didn't say anything about relationships either...
Attracting gold-diggers can be fun if one sticks to pump & dump kind of debauchery. It might seem unscrupulous, but we're not discussing that. Worst-case scenario, one risks getting one of these gold-diggers pregnant... and be forced to see her again (or, preferably, her lawyer) in the future, which is never pleasant.
