Draw up a buying shortlist of possible cars.
Drive as many cars as possible, don’t simply sit in them.. DRIVE them!
Check car running costs and residual (resale) value before buying
Compile a list of questions to ask in the dealership BEFORE you go in.
Be objective, there are plenty of cars to chose from so this is not the time to get emotionally attached.
THE BOTTOM LINE
Know what you can afford to pay, and don’t allow the temptation of something new, better, faster, or sportier to make your decision.
