A friendly piece of advise -
I always recommend taking a buddy with you when buying used. Taking the wife is fine but you want someone who Is not emotionally tied to the purchase.
Explain to that person they are there to point out everything wrong the vehicle, the deal and even the way the salesman is dressed. You want someone who is objective and will not hesitate pointing out things to you. They need to be on their toes and explain you buy them lunch or dinner as soon as you roll off the lot. Every time the salesman or sales manager asks who I am when I do this, I politely explain I’m there to help keep them honest...they hate that as they know it is an unemotional set of eyes on their deal.
A fresh set of eyes and constant advice from a friend during the buying process can save you a ton of grief later. Ultimately, you as the buyer make the decision but it’s my job to ensure you have all the facts available to you so you can make a sound decision.
I’ve done it for my kids, relatives, coworkers and friends, and I’ve always been thanked afterwards…whether they purchased the vehicle or not. It is amazing what you see, hear and feel when you aren’t the one making the purchase.
