I've gone in for mere leak checks on my 06 Acura RSX and they didn't charge me since no leaks were found. A grill piece keeps popping out, which they popped back in at no charge. I also needed to replace the rear wiper arm and tried to remove the old one myself, but because it was stuck on for 10 years, couldn't, so I took it to Car Nerds. They sprayed it with whatever loosens rust, at no charge. Don't get me wrong, they will charge for actual repairs (competitively priced, of course), but when they do, I feel like its money well spent. I completely trust them with servicing, from oil changes to the 30k services. My RSX has over 170,000 miles and still runs like new. These guys completely earned my trust--I highly recommend them.
