Greetings to all,
I own Tata Indigo TDi LS variant, which became part of my family on 28th October, 2005. It came with a price of 5.3L on road.
Add-ons:
1. Lucas TVS 90/100 headlamps (blue light) later switched to Philips.
2. Pioneer MP3 player with 5 way speakers.
I had bought this car hoping that I would be doing lot of highway driving, which I continue to do even now. Never really had any serious problems with the car except for sligher higher engine noise than similar dated tata indigo's and few rattling noises within the passenger cabin esp from the dashboard. Apart from all these minor issues, car has lived upto the expectations interms for drivability, fuel economy and comfort.
This car is good to drive in city, let it be taking U or doing a sharp turn is not a problem at all. On weekdays I use my car hardly for 10kms a day but during weekends I havent taken a count of distance travelled.
Highway driving has always been a pleasure with Indigo, I have ripped the car for 10.5 hours of non-stop drive from bangalore to hyderabad (580 kms to be precise). This happend way back in December 2005, when I was travelling to Bhilai for my engagement, I had to catch a train from hyderabad, as I had missed one from bangalore. Trust me I never had even a iota of strain or stress doing that. Car is great interms of maneuverability and handling. I have a reason to praise for Indigo's handling, rear right tyre went flat (curse the nail) near Kurnool on my way back to bangalore. I was cruising at 130 when it happened. Car went bit off the straight line, but I didnt have problems in controlling it. Thankfully front tyre didnt give way, otherwise I wouldnt be there today to give this report

.
I had two minor city accidents, firstly when a LPG cylinder tempo rammed into my car from back, I trashed the licenseless driver and made his owner pay for the damages. Second incident was when a Marunti 800 drunk/licenseless - 'learner' banged my car in a cross road which resulted in the suspension bend. I managed to extract 8k from the driver to get my car fixed. Luckily rear struts costed only 6k + labour, I had to pay 1k from my pocket.
Regarding diesel I have always been particular. I usually drop in at SHELL(old madras road) or HP (airport road) stations. I have been using System D frequently, it has helped in the reduction of black smoke emission from the exhaust.
One tip I would like to share with all Tata Indigo TDi owners, run the engine in idle for 5 mins after cranking (i know it sounds crazy and more than what manual reads), I bet it helps to reduce vibrations and heats up the engine. I make it a practice as my city usage is quite low.
I would like to know from fellow Indigo owners, is there any K&N filter available for Indigo.
Suggestion to Tata, it would be great if Turbo charges kicks off bit early then what its currently. I believe Tata uses KKK turbo charger for Indigo, these chargers are not that efficient, I wish they have better alternatives.
In summary, Tata Indigo TDi LS has proved to be a great buy for me. I have read articles about its drawbacks, but I would say in short, "what you pay is what you get". This car is good value for money and I bet it can give a good run for money as compared to petrol cars of similar price tag.
