Car List
Expats tend to:
1. buy a second hand foreign car from any one of the second hand car dealers
2. buy a new Malaysian made car such as the Perodua Myvi.
Imported cars in Malaysia are extremely expensive. Malaysia produces its own cars such as Proton, Perodua and Naza which are more affordable. Some expats steer clear of the Malaysian made cars for fear of safety and quality whilst other expats are very happy especially with the small Perodua Myvi.

Second hand Hondas tend to be quite popular. A new Honda costs 115,000 ringgit upwards (approximately: $39,000 US).
A second hand Honda can cost anything between 37,000 Malaysian ringgit to 100,000 ringgit.

I did my driving licence from scratch here in KL. The process was smooth but required as usual a theory test, driving lessons and a practical test. I now have a probationary licence that allows me to drive around for the next 2 years. After that I can qualify to have a full licence. This is the system here.
As a learned driver you can convert your licence to a Malaysian licence at Putra Jaya, the administrative capital in KL but the rules keep changing. You may or may not have to sit a test.
Some reciprocal countries can use their licence for a couple of months or for as long as it is valid before having to convert. UK licence is one of these.
