The workshop
A London Street fixture since the mid 80s.
John Collins founded JC Autos in the mid 1980s and ran the workshop himself for decades, building one of the most trusted names in Whanganui motoring. The shop is now under new ownership, with Jack carrying on the same way of working: explain the problem, agree the price, do the job right.
That approach is why the workshop holds a perfect five star rating across 144 Google reviews. It's an MTA Assured workshop and stocks Shell lubricants on site.

"Highly recommend JC Autos! Jack was super responsive, honest, and transparent from the beginning. Before doing any work, he clearly explained the possible issues and pricing. He checked everything thoroughly, kept me updated the whole time, and never tried to upsell unnecessary repairs. Very trustworthy mechanic, fair pricing, and great communication."

"We had issues with our car while in Whanganui travelling from Palmerston North today. Jack very kindly diagnosed and fixed our car on the spot - all during the time it took us to have a coffee. We were able to continue our journey home and were extremely grateful. You guys are awesome!"
