there is no arguing that computer controlled engines are more efficient. but they have a ton more parts. eventually all parts fail. if you don't have a part that part will never fail. therefore I feel older vehicles are more reliable, if you have the right vehicle. sure a newer vehicle will go 200-300k, but then what? I have turned the odometer over and over and over many times on older vehicles. if you pick the right older vehicle you can keep it going forever, just rebuild front to back it every 10-15 years. I am in the process of doing this on my 1978 right now, it's the second time I have done this the last time was in 2000-2001 when I first built the truck. yes I built it, the last time I counted it had parts from ten different trucks. after this round of rebuilding I will add 2 more trucks to that number. highdesertranger
