Me too, i only repair cars in my own garage for hobby and a little additional money. When today someone come with a car newer than 2005, i tell the people: This is a disposable product that cannot be repaired.
I mean, come on, these engines today. Downsized turbo engines with 500 sensors, Camshaft adjustment, adjustable intake manifolds, with swirl flaps, DISA, secondary air systems, particle filters, ad blue and all that rubbish, ensures that BMW, Mercedes or VW engines only last 100,000 miles, but are not economically repairable.
I love my LS engine, this is a truly good engine, build to last and build to be fixable..
That is good for environment....
