I went and got tested by Rancho Smog today and the fellas who work there are polite and straightforward.
With a coupon I only paid 38 bucks for my test. I failed because I forgot that I needed my dipstick fixed and I went and ahead and got that done within the next hour. Came back, got the free retest, bam, passed. The guys are quick, efficient, and even if it does get busy you won't be there for more than 20 minutes.
If you read complaints they simply are coming from those who drive large vehicles and everyone knows the larger the ride, the more complex things may get. I also find it humorous that there's someone complaining about having to have paid $49 with coupon, and calling these guys a rip off. Everywhere else will charge you 55-60 bucks even if you were to bring in their respective coupons.
For those that have a hard time finding a coupon for Rancho Smog just google one and print it out or look in the Penny Saver.
