if you dont know how to check the cars over yourself or are in no way mechanically minded then i would think twice about going into car sales at all mate unless you have some good mechanic friends who can at the drop of a hat check over any vehicle you will be buying before you buy it, as a lot of jobs on cars nowerdays can easily exceed 500quid yet there are very few cars these days that you will make 500quid profit on so you have to be very carefull picking cars as you would soon go under if cars were coming back needing work that cost more to put right than the profit you make!
plus bare in mind we are not even into the middle of the recession yet, i forecast at least another 7 years before we are out of it and while times are hard you will find the motor trade a difficult place to be in, trust me i own my own garage and im happy at the end of the month if i break even at the mo!
