used tata indigo cs dicor whether to buy or not

a friend of mine has tata indigo cs dicor for sale , he is expecting 3.8 lacs, run 12000 kms, single user bought in 2007. I heard that dicor has more maintenance cost, is it so, is it worth buying the car  for us we are all bulky in our family, so i feel indigo cs can accomodate easily. my avg usage will be around 30 kms in a day. Please suggest me as I am confused

If there are ECU problems with the Dicor, they can be tricky and expensive to solve, even if the car may have ext warranty. Why exactly is the car being sold so soon?

Also, your information is incomplete. There are was no Indigo CS in 2007, and dicor was launched later

What do u mean by ECU problems, he has got another 2 cars and he is telling that he has no use for it now. MIght bought in 2008 driven 10000 kms

the ECU is the electronics which control the car. they/the sensors might have problems leading to recurring check engine light being on, and the mechanics having not much idea what to replace/how to solve. Even tata mechanics arent as familiar with Dicor

Thanks for your reply, I am actually confused the thing is that my daily usage will be around 40 - 50 kms and diseal cars are more than 4 lacs if i buy a new one, so that's the reason I am gng for second hand one. I don't know what to do? Csn u please help me
