I live in Bahçelievler in Istanbul. What if we meet a few friends and use our vehicles mutually and compare their driving on a suitable terrain (such as large shopping malls like marmara forum)? I observe some problems in my vehicle, but I think these are normal or not, I cannot understand without using other tools. Are there any friends we can meet in this way? 
 Meanwhile my car is tiptonic gear.
