Having sold a number of larger items stomper I understand completely what you are saying. I look before I bid or offer as well....

and.. yes you are right many offer becasue they cannot "look" till the weekend so they close down the auction or BIN...... very common...... if you do a completed listing search results at items nearest first and use your own postcode in the car category you will see relist after relist after relist with the owners getting chittier and chittier each time and NO SALE

Almost every vehicle ad has something like " no time wasters' or "you are bidding to buy not to look" or "tyre kickers jovially shot".... because plainly there are a million dreamers out there who sit at a computer and dream about the maddest, siccest chariot on earth  that they cyber owned for that fleeting second
