The price looked suspicious at first. I took a "risk", bought a coupon, went there this morning and got my car checked in about 15 mins.
Result: No issues found - got my e-Check submitted to RMS NSW (former RTA).
Normal price for e-safety check there is $29 by the way, which is also competitive.
Groupon deal sounds like a bargain.
*LPG System check not included
Don't forget about cashback via shopback or cashrewards - whichever has a better deal at the time of shopping.
Cheaper than throwing a slab of beer at the mechanic
