If a guy have the above mentioned sport car, stable high paying
job, rent a condo and average looking, this guy do not need to come
to www.sgforums.com to look for female lunch buddy. Alot of women
will flock to the guy. 
The above actually poses 2 logical problems:
1) We live in the REAL WORLD.
2) Any sensible female will know that this is absolute bullsh*t, as
provided by the reason above.
So in overcoming the logic errors, you can:
1) Start living in the REAL WORLD.
2) Be more honest and sincere. No sport cars, condo or high paying
job can beat honesty and sincerity in the long run.
