Have to agree with 155lee tbh,generally found it ok but obviously still a lot of cocks on there.
I find it best to put only a number up and I tend to refuse to bother answering messages on there unless it's regarding buy it now as IMHO if your interested you'll phone.
Got to be honest the worst I've found is pistonheads so far,ive put some really well priced cars on there without so much as a sniff.
