I can always relay on my Lada because it's made in Russia and it won't ever surprise me in a bad way.
Parts are very cheap to buy, however in 24 years of owning this car I have never done any major repairs, only just the little ones.
This car is fast for its age, even last year I was nearly having a heart-attack when I noticed that the car's speed was 170 which is very good result for even a 2 year old Lada.
The engine is very good. It started in the winter with -25 degrees Celsius. Can you believe it?
The one and the only fault in this car is its radiator. It must be replaced in every 2 or 3 years. All the rest is best. When you think I'm not writing the truth, then try it and you won't regret it!
Well, I didn'y notice any problems with the radiator, until after 20 years it got rusty, so I had to replace it. However it has a major problem with the interior heating valve, I've replaced it million times, but it start to leak over and over again.
Yes!
I'm an owner of the same model LADA 2103 from 1976.
Really - this is a nice and friendly car:)
Pawel.
My 2103 has got the original radiator, but I share you view on the heater valve, but if you use a good anti freeze like the one from Mercedes Benz then it should be OK. It worked in my car as it's only had two valves in 25 years.
Regarding your radiator - I suspect something in the water you are using and/or lack of a suitable antifreeze. I still have the same radiator and heater valve in my 2103 after 200 000 mls without any problems (I also have 2 much older cars than my Lada, both of which still have their original radiators too). You must use a good quality antifreeze and boil any water before you add it to the radiator. This removes any chlorine that is often present in tap water and which can cause corrosion.
My BA3 2103, acquired in 1976, has been excellent, but I suggest that the mechanism of the clutch is studied, because it is the cause of many problems. Also, the hinges of the doors loosen. Nevertheless, I consider it an excellent car.
