Beepkart reviews ??

Considering buying a used bike / scooty from beepkart. here are a few questions I would like to get answered :

1 how well do they refurbish the vehicles ? is it actually durable from within or they just make it look good ? 2 their price range seems to be ~50% of the new vehicle price. is that good or are there some better options ? 3 how are the other competitors as compared to beepkart ? 4 how is the purchase and service experience ? do they actually provide 3 free services ? 5 how is the experience around ownership transfer of the vehicle ? 6 are there any other hidden charges ?

thanks !
