10 years experience.
Previously was at $60 an hour Master Cert Bugatti, Lamborghini, Bentley. 40 hour guarantee. 5 years experience with those brands.
But recently left for a less stressful brand for $50 an hour, but book more hours and have way more free time. And basically zero warranty work. Mostly CP and Internal. With 40 hour guarantee.
I personally will never work somewhere without a guarantee, dealers can afford a bad week every now and again.
