I have decided to buy the Sierra Adventure Plus variant. But should I go for a diesel automatic or a petrol automatic? Please advise. My running is less than 6000km per year.

I have brought one TATA Sierra adventure plus Automatic Diesel I took delivery on 10th April 2026 from 11th early morning till 13th evening I was on travel drove 1200km it's amazing experience and I did not feel tired, the car is of world class product. So far I have shared the product quality. Having said that coming to service side from the authorised dealer though in one way they cheated, why I am saying is before selling their commitment is extra ordinary and after sale is concluded they back out from their promises, in my case they committed under chassis coating Free, discount on essential accessory and delivery of the car in weeks time after full and final payment. They did not keep their commitment in delivery schedule they took 10 days after full payment,
Autocar would you recommend tata sieera adventure plus diesel manual ?
Don't buy if you are a first time buyer....I have adventure plus diesel....pick up is very poor and vibration issue at 2nd and 3rd gear
After 1200km I took my car for 1st free service i had experience few issue to be resolved in that 5 days I noticed they have delivered the car to me without fulfilling committed job of under chassis coating, I had opted for roqkit the pasting of these accessories were very poor, they have not wiped excess glue on the surface of the car, some parts were not pasted properly. It started to pieling off, door visor was not fixed properly with double side tape, and these was brought to their notice during 1st service, these guys are not bothered to resolve our issue rather they want to promote their value additional service during 1st service than solving the existing issue, they did not rectify what I had highlighted while preparing job card, they said those will be take care by respective departments. I received the car after 1st service in same condition that I have to them. In the meantime they want me to for ceramic coating extended warranty etc which they get seperate margin What they committed they never fullfill, all youtubers only review about product they never say about the service providers review, more than product i feel the youtubers should give review of service providers aswell. How ever I got the car of my choice and dream i am worried wether after sale service will be like giving garland in monkeys hand.
As per my knowledge from you tubers or Tata customer experience, customer said Tata product is good but service is average or not good. So some Tata customers keep looking for better service centers. I have come across some mechanics working in branded company like Maruti, Hyundai etc when we ask solution or issue, they will give some irrelevant answers thinking that they have given the right answer. Real incident i had faced is i had asked company technician to turn off Adas future. In case if he couldn't solve the issue he should have checked with their couligues to solve it. Instead he gave some wrong information. Finally Car manufacturers are coming up with new technology but service engineers are not getting complete technical knowledge from company. So customers are facing issues
I have booked the Sierra Adventure Plus petrol MT. But now on considering the milage and pickup, I am confused between diesel MT or a petrol MT? Not interested in AT. Please advise. My running is less than 6000km per year. Or any other spacious and good mileage car that you would suggest?
