well, even your car could do 110mph, please do not speed in public road.
1970 cars are pretty much lagging behind in safety features such as good brake, suspension, tyre grips (if standard trim that is) etc. The 1970 chassis design is not as good and strong as today's car. In addition, after 30 years of age, the car's structures tend to weaken due to rust (most likely)
So, if anything goes wrong during the high speed driving, I think it will be veeeeery wrong...
Drive carefully, and keep the car nice. it will be a gem seeing this nice classic in Malaysia road.
