Good Afternoon Chaps, Newbie Here

[EPV 631]

Newbie to the forum and something of a newbie to the trade. I'm part of that "build up my business part time" brigade I'm afraid, been going about 3 months and sold 3 cars (all in January incidentally, has someone died in February? The motor trade, possibly?)

I've been a lurker on here for a while now so thought I'd sign up and join in. Some really useful stuff on here so a collective thanks to everyone. 

My website is here; www.elitepreownedvehicles and I'd appreciate some critique of my adverts, I currently have 4 up for sale, all clean low mileage stuff (which is where I focus my attention although I'm tempted to start selling some of the lower end stuff as some on here seem to do well) but I've not sold a thing in almost a month now and I'm getting a bit impatient, anything obviously wrong with these?

I've got an ebaymotorspro account, I also use Motors.co.uk (although cancelled that as I don't think it's worth a carrot) and I do also use PAYG Autotrader.

Cheers in advance for any advice!
