What Our Customers Say

A big big thank you to Tony, an old school professional and a gentleman.

He got us out of trouble when our rental caravan split its radiator and we had a trouble free time for the duration of our stay in NZ.

Thanks for your assistance and a pleasure meeting you. Best regards.
Lee & Anne M.
Fantastic service - called in the morning with radiator leak and was sorted out within a few hours.

Highly recommend. Thanks Tony
Chris B.
Top Notch! My motorcycle has a complex curved radiator, and it developed a hole in it.

Tony was able to patch the hole perfectly for such a good price, very quickly!

Another hole in a different place a few weeks later, another patch, another job well done.

Now the weakpoints on the radiator have been patched, I've had no further problems. Thanks Tony.
Samuel A.
I had a problem with the radiator overheating and arranged with Tony to take the car in to him at 8 oclock the following morning.

I had it back by lunchtime repaired working perfectly no hidden extras.

I found him very reliable and honest, a rare treat these days. Thank you.
James & Sandra K.
Fantastic service when I broke a radiator mount on my Motorhome.

They were friendly and helpful, and gave my job priority to get me back on the road again.

I couldn't recommend them more highly.
