Hi everyone I need some advice. I'm looking to buy a 00 new edge and my budget is 7500.00. I found one I really like went to see it checked it out and noticed when looking things over it wasn't registering oil on the dipstick, 2qts later and it was good. Besides that everything seemed good just normal older car stuff. When we went on the test drive and got on the highway whenever i downshifted then floored it I noticed blue smoke out back... Now both me and the owner were upset over this he obviously wanted to sell it and I drove quite a ways to buy it. He never notice this because it's been in the garage since November and since it doesn't do this when driving normal or even when you drive it a little fast. My question is I might have a chance to get this car for 2k, could I get a motor and have it installed and still make my budget work?
