RJ is becoming a joke with guys asking rediculous amounts for their cars, parts etc. If you think your car is worth so much, then taking the time to send enough info, (pics included) to justify said asking price shouldn't be an issue. Selling on any site attracts every yahoo looking for a bargain, look at Craigslist. Lots of buyers here are just looking for a car to flip at your (seller) expense.
If you cannot stand to deal with clowns, then don't try to sell to clowns. Its the nature of the beast. Get over it and move on.
