Re: Purchasing a Car from Mumbai and Using in Kolkata
@pinekel - From my experience, in the 90s my uncle brought a Omni van from Gurgaon to Kolkata (transferable job). He used the same number till it was time to renew road tax. At the time of renewal, he had it updated at Kolkata RTO and got WB number etc. However that was in the 90s, so not sure if that has changed. However I do see quite a number of other state number plates at the office parking and quite sure these people have been here for long.
So probably the assumption that you have to change the numbers within one month of bringing the car here might not hold good in all cases (for e.g what happens if the person is on temporary assignment). However there might be a process of waiver.
Now on the question of registering a old vehicle. I think its possible if the car is going to be used for personal use only. My family had and maintained a 1986 maruti omni van (till 2012 - 26 years) and never had any issue with road tax/regn renewal.
In fact there are lots of vintage cars that are road legal and they are not even BS 1
. So the process exists. Just get in touch with the RTO at Beltala or with a reputed agent if you are not in Kolkata and he will tell you the process.
