Exactaly. My First car was a VL Calais, and it had alot of electrical faults up till when i sold it. My R33 on the other hand, has been so much more reliable. It all comes down to how the last person treated it and the condition of the parts. Best advice I have, is fix stuff before it breaks. If I notice anything even a little bit dodgy on my car I replace it straight away. It saves you in the long run
But as above, Make sure its had a 100,000km service done and unless you know for sure (or have already done so) give it a good service. Im talking spark plugs, engine oil, gearbox oil, diff oil and go over it to find any other problems
