Hi, Ist of all if you know nothing about 2nd hand cars take someone with you that does, as stated do not hand money over, you pay what you see on the windscreen, your trade in price is sod all, if you have one to trade sell it private you will get a better return but make sure you sell it with the truth or you may come unstuck, Always check the history of the car you buy & dont delay in doing that, dont bye when its been raining ( No i am not been funny) check the condition of the drivers seat for wear especialy the eves of the seat this can cost a few bob to replace, Its not so often you will get a chance to try the car out as they are packed in like sardines, the warrantee they give you is a month so think about it, I know what I would do, But I like to barter for everything & you know, It works, there are that many cars out there & you have the last say because its your money they are after.
