Lately I been thinking to buy a new car, but my parents advised me to use back the old car to save money. The problem is that old car everything just feel sucks, no power bad suspension, bad design, bad control, bad sound system, and old tint. The current car I'm using is an 10 years old 1st gen myvi. I'm not sure should I invest my money to refurbish the car, *hopefully the can get back to at least 7/10 condition. To fix all those problem I mentioned, I think probably need at least 5 to 10k I guess. So in my opinion, buying a new might just save the hassle no worry about other thing. What do you guys think?

Refurbish the old car or Buy a new car?

Will the old car become nice to drive and use if I refurbish it?

Does it means if i spend 5-7k, it will be good as new? For now when I drive the car I don't really feel comfortable in terms of the suspension, body frame, stability, and the door sound isolation rubber are like loosen and it hard to close the door ><
