Majority of that list was due to failure. Cost was because I would always bring it to Mercedes Benz of Manhattan to repair it. Biggest cost was new hydraulics for the top. Started using a local MB mechanic but he cannot figure it out. Therefore tomorrow I am driving her back to MB of Manhattan and let them fix it once and for all. Kind of PO at the local mechanic as Mercedes is all he repairs in addition he has been in business for 25+ years. You would think that he would know from experience alone.
