hello mailman,What's wrong with it?
You can bring your 451 and 453s to MB Westminster but they won't touch 450s.
Mainly because they don't have the MB Star Diagnostic for European models.
I asked what's wrong because most good mechanics won't touch them because anything engine related usually means dropping the motor to get to the fix.
I even bought a UK MB Star so someday when I have time I can tackle some things only a MB dealer in Europe can do.
But PM me, depending on the issue (purely mechanical) I have a few trusted mechanics that have worked on my 450s.
They are close to I25 & Evans.
