Compared to most cars of the last 10 years, the 4C is dead simple, and they seem to be quite reliable as well. Yes, there are electronics but fewer than most other vehicles by virtue of the basic nature of the car.
The carbon fiber tub is where all the structural integrity lies within this car, and I've not seen any indication that will degrade if taken care of properly.
I'm not against the 4C. I tried one on at a Concorso a few years ago. Took quite awhile for me to get in, and longer to get out. But, allowances can be made.
It may be entirely an invalid comparison, but when we look at the older Alfas that are commanding really impressive prices today. All of them were worth spit at one point, and so it was not worth it for someone to "take care of properly". Whether it was being kept in a garage, or doing a correct repair on a suffering sill structure, a car worth $500 just gets a bandaid until it can't drive any more.
Name one Alfa in the late 70s that was worth enough to get real maintenance money spent on them. 8C2900? Maybe not even them, really.
So, I fear there'll be a time in about 25 years when the political putsch is on to outlaw gasoline cars, and human-drivers. Cars like the 4C will be not be allowed on the roads in California, so will be sold for a song to people in Texas, Montana, and North Carolina, where SBC will be dropped in at the first sign of a short-circuit. Not long after, that car will have a tree growing up through the floorboards.
I think it's a cool car. I'd like to have one, as my 10th car, and I'm currently up to four plus two motorcycles.
Now.... In 60 years, the laws will be relaxed in the backlash against the tyranny of political correctness, and there'll be about 8 operational 4Cs left in the US. They'll be prized and expensive.
