Buy Second Hand Car or Grab/Uber

Hello,

Need a bit of advice. I'll be moving to KL and am planning to stay around Jln Ampang/Ampang Hilir area and my workplace is at Ulu Klang industrial estate. I should be working regular hours (weekdays - 8 to 5). My questions are:

• Would it be more economical to buy a second hand car (all costs included ie road tax, petrol etc) - locally made or to use grab/uber on a daily basis (to and fro)? Based on initial estimates from a website, fares range between RM 5-8 per trip (excluding surge during rush hours so expecting it to me higher in reality).
• Any experience with obtaining grab/uber cars in these areas? To and from jln ampang/ulu klang industrial estate?

Thanks a mill.
