A relative had leased a small car with an option to buy . Is the final 'buying figure' negotiable?
If she didn't buy it then it would probably go to an auction and the dealer would hardly get the final buying figure.
What percentage of the final figure should she offer?
Sounds like the way I bought my last car (very stupidly). with the monthly payments and the final balloon payment, the total figure paid will far exceed what the car is worth. I would advise her to check the documents very carefully. If the car ends up sold at auction and the price they get doesn't match the final price she was asked to pay, she might be made to make up the difference. It's a bad way to buy a car. I learnt the hard way.
leasing isnt always a bad option, often the payments work out less than the depreciation of the vehicle.
Answer to your question yes it can be negotiable but you really need to know the current market value of the vehicle obviously if its a retail sought after type vehicle they are not going give too much away ,
