    These guys are AWESOME. I took my 2007 H3 Hummer in and they were able to quickly identify some of…read morethe issues. They recommended some fixes and were extremely honest. They completed the work when they said they would and within the price estimates. Great Service from honest people!

    Honestly. They fixed my car a year ago for a water pump and over heating issue and then my car…read moreoverheated almost exactly a year later. I came in to see what happened and they said that the little plastic coolant pipes that go to the water pump were dissolving. I'm honestly quite annoyed because I feel like this is something that should have been noticed a year ago and I highly doubt this wear and tear appeared in a year on a car that already had 170,000 miles. I ended up going to another guy that actually cares about older cars (mine's a 2006) and he figured out it was another gasket in my engine, not a head gasket like they were claiming. Applewood wanted to charge me $4800 in total for a car I paid $3000 for. My mechanic was able to do it for $560 because he just replaced the radiator cap and plastic gasket that gets worn down at almost 170,000 miles each time. I also am a woman so when I called them they used a very sarcastic tone with me and kept gaslighting me on the issue. Sure a head gasket repair may have fixed the problem but I would have wildly overpaid. I added my inspection report that was wildly overstated and would have costed me $4800 for something that they should have already replaced or told me about considering they had replaced my entire water pump and the hose connecting to it.
