I was thinking today about all the smarts that go kaput around 60-80k and the solutions of some people who add roadster parts to get their fortwo to go to 80k before grenading but... What about other options? I feel many smart owners and future aspiring secondhand smart purchasers would like to keep their car a long time and would be willing to spend the extra cash to do a rebuild right with aftermarket components that could make the engine last 150-200k before grenading. So what are and where are those components? Currently they don't exist and I don't know why. I have seen forged and ceramic coated pistons, heads, etc for mostly high end cars like the supra etc... so that those extremely stressed engines could even go 200k. So why not approach those companies that are already set up to manufacture that kind of stuff and get them to do it for the 600cc&700cc engines so that the new benchmark for smarts could be set with engines being able to last a predictable 150-200k. I guarantee if these parts were available and showed a doubling of engine life then there would be a flock of customers and rebuilding shops offering these new parts. I believe at some point some manufacturer will take on this undertaking but I see it happening more in the future as smarts become collector cars, antiques, or classics. Anyone else interested in these non-existent parts? Would you buy them if they were available?
