High Maintenance car - Elite I20

Service & Maintenance (Sharayu Hyundai - Turbhe, Nai Mumbai) Dealers/Service should stop panicking customers and charging them bomb with their secondary business model of selling spare parts. Unless you are die-hard fan, don't go for Hyundai. I-20 is known for its poor mileage but still has its own buyer because of its looks and on-road performance. Hyundai and its dealers has promised to deliver better mileage (lets say ignore) and low maintenance car while making sales pitch. Car maintenance schedule and spare part price listed in show-room promises low maintenance cost. But this in fact is to fool you. This is my first paid maintenance experience. All my free service was smooth with minimal charges of oil and filter etc. The moments I parked my car for paid maintenance in 6 months from last free service adviser listed me a whole lot of parts which needs to replaced and problems with car. In 6 months @25k KM they have list of Items to be replaced costing ~10K INR. This is Hyundai scheduled maintenance - Do this manufacture use such low quality parts and built is so poor? or its dealer who made it a secondary business of selling service and spare parts each year cost 12-15K to customer. (this time for me Parts -5K + labor ~5K + Taxes) With Synthetic oil which I used this time, my next service due is mentioned in 6 months or 5K KM. (any logic?) This is high maintenance for hatchbach 1.2 petrol car as per standard. My friends with Honda and Volkswagen cars are more happy customers. Hyundai competes nowhere except looks/design in same category. Manufactures should watch out dealers or loose market.
