I would say add 90k or so and buy REVO 800 CC PETROL Rs. 279,000
10k for registration etc
I know 90k is a big amount but better than spending 200k on such an old car used in Karachi on our roads.
Or buy the Revo and get it financed,pay 50% downpayment.
Use the rest to pay monthly and at the end of it add more from pocket monthly so he wont have to pay the extra 90k at once (though it wont be 90k but will go over 90k easy)
But finance or lease it only if he can pay the monthly and not like pay for 2 years and then cant pay,as it will all go to waste.
