Welcome to a fantastic forum Darren. I'd listen carefully to what the guys and gals recommend and read, read, read! The very best advice is to get someone from the forum to go and look the car over. It may be that this isn't the ideal car but that wouldn't worry me too much, there are good ones around so it's well worth waiting for the best you can afford (like most cars, so sorry if this sounds like trying to teach granny how to suck eggs!).
Read the buying guides and ask as many questions on here as you reckon you can get away with
Once again, welcome to the forum, I reckon you're going to enjoy your time here!
