The guys are engaged in repairing engines, chassis and simple work on replacing components in the brake system. There is a service to strengthen ball bearings and other suspension elements.
I have been served by them for more than 15 years, everything is fine.
Craftsmen make engines and walking gear. They work well. Some undercarriage parts can be reinforced and give a minimum one-year warranty. They strengthened my balls, they were gone for 5 years.
And another advantage is that they do not climb where they are not experts. For example, brakes: the maximum they will do is change the pads.
In general, well done, guys. It's not for nothing that I've been visiting them since 2007.
