    I'm in the process of selling my electric vehicle. I loaned the car to a potential buyer who took…read morethe vehicle to Rob's for a presale inspection, which included using an OBD diagnostic tool to check the vehicle status and look for fault codes. The vehicle did return a handful of fault codes, which the buyer had understandable concerns about. However, ultimately some of the faults were outdated and could be cleared without issue, and the remaining faults were all addressable. The main issue was that Rob's reported the "battery capacity" to the buyer as "about half," which was an immediate deal breaker for the buyer. When he shared this with me, I was deeply confused, as the range of the vehicle is still close to 100% of what it was when it was new. Using my own OBD diagnostic tool, I confirmed that the battery health was near 100%, and that's when I realized what had happened: the technician at Rob's had misinterpreted the *current* state of charge (which was about 50% at the time of the inspection) as the batteries total capacity. Figuring that this would be a simple matter to clear up, I called Rob's and spoke the the technician. From the moment he picked up the phone, was combative and indignant, and refused to acknowledge the error. When asked if I could come by to have the car scanned with a fully charged battery to confirm the error, he said he would charge me for the full cost of another presale inspection. The mistake of the technician and total lack of accountability cost me the sale of my vehicle. If their techs don't understand the difference between a battery's state of charge and total capacity, I certainly wouldn't trust them to do any work on my vehicle. Recommend looking elsewhere.

    This is my go to spot for a few things including but not limited to: diesel gas, 10 lb. bags of…read moreice, air for my tires, car washes, and last but certainly not least King Size Nutrageous bars. It is conveniently located to downtown Boulder and has a large island of gas pumps. There are a few parking spots right in front of the store that make it quick and easy to bounce in for whatever I may need. This location circulates coupons to those of us who live nearby and the hours just cannot be beat. Staff are courteous and efficient though not big on small talk. I'll definitely continue to drop by for my candy bar fix!

    My regular car wash gas station has been malfunctioning for months. I/my car got trapped inside the…read morewash covered in soap one time, when the machinery stalled. The last time I was in, it was shut down for a complete rebuild (it was very old) and to open at some point next month, I think they said. Anyway, my new car, now a bit over 2 months old, was finally ready for its first wash, a perk for buying a color that is perfect Boulder area "dirt" color. But needing to climb against the sides of it soon to get the old ski rack on, I decided it was better to wash it first rather than transfer all the dirt to my clothes. I tried this place, despite the only other review because it was in a convenient location, it was 60 degrees on a sunny afternoon of New Years Eve weekend. Seemed like a decent idea. By my standards, the cleaning was just fine but not perfect. Just a little (2") stripe of residual minor scum along each side panel. Wiped right off with a cloth. I think the side profile of some cars just get that as my previous Outback did too, but not my flatter sided little Scion. The car looks good for a $10 wash.
