Hi Tassell Team, I just wanted to say thanks for the outstanding service you provided last week. We have been using Tassell Automotive for a few years now and when my husbands car was "making noises' while I was driving it last week I made the decision to take it straight to the boys at Tassell. Guy popped it straight into the workshop, communicated the problem to me immediately and went about ordering the parts......the car was back on the road in 2 hours. Thanks guys, great communication and oustanding service. See you again.
I have had my vehicles serviced by Guy for many years. Having owned a range of vehicles including HSV Holden, Mercedes and Porsche, I have no problem trusting Guy to perform to the necessary standard required. He has all the latest software needed to service my vehicles. Since I have now moved interstate, I am no longer a customer of Guy's, however I highly recommend him to others.

Michael Syms , Dural, NSW
To whom it may concern, I have been using Tassell Automotive since it commenced back in 1987. I have always found Guy and his staff to be incredibly helpful and knowledgeable. What impresses me most is the way in which they intercept potential mechanical problems to ensure me of safe and reliable motoring. Over the years I have recommended numerous people to Tassell Automotive and they have also formed the same opinion. Simply, good honest service with exceptional mechanical knowledge

Stuart Bow , Director, Turfscape Solutions
I have been a client of Tassell Automotive for over 20 years. I have always found the team to be profession, efficient and reliable, going above and beyond to meet my needs, whether it be a minor service or major works. Guy and his staff are to be commended on their mechanical abilities and customer care.
Adrian Apostolatos ,
Personally and along with my business have been using Tassell Auto for close to ten years, with numerous vehicles of all makes & models. Over this time I have known Guy & his team to exceed my expectations & industry standards for service & workmanship. I would have no hesitation in recommending him and in fact have already done so. Cheers.
Mark Halford J.P. ,
I have had my fleet of company vehicles and personal cars maintained and serviced by Tassell Automotive for 25 years. During this period I have received nothing but 1st class advice and service. It is pleasing to deal with a professional organisation that delivers on its promises. We often update our vehicles and it is pleasing that Tassell automotive are able to provide tooling and resources capable of handling our modern fleet. We are confident that Tassell automotive is a one stop shop, who has the time to run between vehicle servicing, tyre providers or even auto electricians. It is pleasing that the run around is completed for you. We have nothing but praise for Guy Tassell. Congratulations for providing a modern well run workshop. Regards
Michael King ,
We were introduced to Guy from Tassell Automotive approx 6 years ago and have taken our work and personal vehicles to them ever since. We use to use the dealers to service our cars but never felt confident they were looking after them properly and honestly. Guy has given us confidence with looking after our fleet and has helped keep them on the road without any mechanical failures. I believe that you can judge a business by the way they present themselves and by simply having a look at the way Guy and his staff keep their work shop and office says allot about the way they operate. The service, workmanship, pride, honesty of Tassell Automotive is evident in everything they do and is why we trust them to maintain our vehicles. I don’t often recommend anyone unless I feel they are very good at what they do but I’m happy to recommend Tassell Automotive to anyone so much so that I will be happy to speak to anyone that is considering Tassell Automotive for their automotive needs.
Neil Merrin ,
After many unsatisfactory services at various locations including dealers, I was referred by a friend to Guy Tassell. As a family, we now have 4 cars under the care of Guy and problems that were plaguing our cars prior to going to Guy were resolved. Everyone I have dealt with at Tassells have always been helpful and informative. I would recommend Tassel Automotive to anyone without hesitation.
