I purchased my first car, a 2003 Cuore, three years ago. The engine is still in perfect condition, but the body has deteriorated significantly. I want to upgrade but can't afford to spend more than 2-3 lakhs. I have three option Cuore, Cultus, and Alto in this budget, I don't have other options. Please advise me on whether I should keep this car and continue using it, or sell it and add some money to buy a newer model of the Cuore, or switch to a Cultus or Alto. Thank you.
