I have three vehicles that Calderon services for me - a current Hyundai, an older Blazer, and an ooooold Airstream. In all cases, they're just straight up with me! They tell me what needs to be done, what can wait, and what I can do myself to save a few bucks. There has been times they've called to talk me OUT of service I don't need yet. There have been times I've told them to do whatever they need to do... and they call to tell me nothing needs to be done! The only "con" I've found is that they do charge a premium for parts - basically List vs Retail - but in the context of what they've saved me (knowing they're only doing what NEEDS to get done), I'll gladly pay for their expertise - which is why you take your vehicle to a mechanic, right?!?!
