Like we said, we are specialists to find quality used engines. We’ve hundreds of engine 
suppliers inside our networks and we’ve an excellent system for quality control and accountability. In enough time it takes a mechanic to contact several of his buddies, we can get you rates on multiple engines from dozens of suppliers and manufacturers. Once we get you a great engine at a great price, we can ship it right to your mechanic’s Driveline Motor garage by freight. It’s a win-win situation-you obtain a better price on a much better engine and the mechanic doesn’t need to waste his time playing mobile phone tag with junkyards. But of program, you can give us a call directly and save even more money.
Either way, you’re likely to pay an enormous sum on a whole new car or dispose of money upon the markup on a utilized engine that comes from who knows where.
Alternately, your mechanic may offer to discover a used engine to put in your car. Again, you will see a large markup on the price of this part-and you may or may not have any state in where he gets the engine from and actually less knowledge about the quality of the engine and the reputation of the car recycler or junkyard that sourced the engine. Many mechanics have relationships with a couple of car yards where they obtain parts and the do little comparison shopping in your stead, which is usually understandable-they’d rather be in the garage than on the phone all day.
The next option that your mechanic might recommend can be an in-house engine. If indeed they provide a good price and are a dedicated engine shop, this may be a good choice. But in our encounter, we’ve found that only a handful of shops that do engines genuinely have what it takes to do a quality job.
Generally, they’ll source it to another repair shop. And when that occurs, you’ll be charged a significant markup, not forgetting the hassle of experiencing to undergo two parties to get status updates and estimates on your repair.
