"Tim and the guys were absolutely brilliant when my Mercedes Sprinter van ended up broken down in Esperance. No one else was prepared to fit me in at short notice but Tim was more than helpful. He gave me an honest assessment and didn’t do more work than was necessary. When he went on holiday one of his team picked it up seamlessly and the communications were excellent. Really appreciate their help" – Lyn Fernie

"Travelling from Melb to WA we had problems with our motorhome. Made appointments with Repco in Renmark who had no idea what was wrong and Ford in Port Augusta who couldn’t have been less interested. Decided to try a real mechanic in Esperance. Tim from SEA Heavy Diesel was genuine, honest and helpful. He and his team sorted a pretty big problem out quickly and efficiently. We are very grateful and satisfied with the job. Many thanks Tim" – Elizabeth Rae
