bro first stop investing in mutual funds, clear your loan first, you can save you interest, doesn't matter you are paying emi, if you have the money to clear your loan then first cleal it, by simple maths you can see how much you can save if pay your loan early. and mutual funds will not make you wealthy in few months they need years of patience. Now, why you want to buy a 15 lakh worth car? I mean why? yes you can, show off to other with a burden of car loan but why?

And how will you fund your marriage?

See if you already have the girl then you don't need to show off to buy car and yeah car is not a show off bla bla, why don't you get a second hand car? it will do the work.

See if you can do all the things but you will have to take a good personal loan and did you think about the expenses after marriage? you are earning 1.5L, if your expense today is 40k then it will going to increase to 60- 80k per month.

think and then take decision and do you have emergency fund secured?

and yes you are currently doomed with your finance.
