Good thread to compare the price of spare and consumable parts.
However I have started a new thread (if needed, can be merged with this) on TCO including vehicle price, spare parts cost, regular service cost, and labour charges. We should also look at the service quality and customer satisfaction as well (thought this will be highly subjective).
As per the excel sheet, Ritz is really VFM followed by Figo. Sheet also indicates that models those sell in low number have costliest spare parts and availability of parts on time is also issue. These are U-VA, Jazz, and Fabia.
In terms of parts cost 5000 here and there won't make much difference to most but labour charges will certainly burn hole is pocket. LC in Skoda, hyundai and VW are higher than say Maruti or Ford (I am assuming which might not be the case).
