Two red flags immediately on the ad.
1. She mentions her rates, but then says she is open to negotiation. A legit SP NEVER negotiates her rate. Either this one is super naive and doesn't care, or its a trap.
2. Most SP's do not do car dates due to it being dangerous. A client could kidnap them and take them to where they do not want to go. Her asking for a ride is a weird way of saying she wants to know you have a car, or she's just lazy and has no incall or doesn't wanna do an outcall.
Either way, too many weird things to consider a TOFTT, in my own humble opinion.
