What would be the most prudent decision for En Hilmy?

En Hilmy Ali is 25 years old and just started working in one of the public accounting firm in Kuala Lumpur subsequent to completing his Masters in Finance. Before he gets married, he decided to make one big purchase in his life, his dream car, Honda Civic. However, he is still contemplating to buy a house instead buying a car as he uses public transport to commute everyday to work and outing.

Below is the detail information for consideration in making the decision:

Monthly salary of RM 4,500, Plans to get married in 2 years time with his fianc, Hunting a house in the outskirts of KL in 40km radius, Works in KL city and Fiance works in Shah Alam
