In theory, as long as you replace parts and as long as parts are findable or available.
Closest thing I can think of is VW beetle or bug many from 1962 are still around and
running, and that is what 51 years. So still around in 2058.
The car I have owned the longest so far has been with me for 25 years and will be with me until I am dead. So it is also planned for my second - my current - smart, which has only been with me for ~4 years.
When I bought my '88 Festiva in the Fall of 1987 folks said it was a throw-away car good for less than 100K miles. Several years passed and folks were racking up +/- 200K miles and getting 40 mpg! While some smart owners have had bad luck with the valve issue, others have really piled on the miles. Whatever you think about Mercedes otherwise, they probably support their older models better and longer than any other mass producer of autos. I have less trouble getting parts for my 1977 230 gasser than folks owning other brands a fraction of that age.
There is a Camaro in my garage that's 45 years old and it looks great. Both of my Isuzu's are '88s. My next door neighbor has a pole barn full of Willy's Jeeps that date back on average to '53 or before and a WWII MB that was made in '42. Most are drivers. Time will tell. My concern is the computers on newer cars. We are rapidly reaching the point of planned and scheduled obsolescence. You take your car to the dealer to get if fixed and get: "I'm sorry sir but you have a Windows XP car and we are no longer allowed to work on that software. The government won't let us. We are only allowed to work on Windows 12 and above cars. I'm sorry but we are required to erase that software and disable the car and junk it. We'd be happy to sell you a new 2025 Smart pure for only $125,000!"
A question occurs: I too, would like to have enough spare parts to keep my smartie running from now on. Say you buy a complete engine (i've seen them on Ebay). What is the prodcedure for preserving said engine until yours croaks? I know people winterize or prepare for storage cars. But what I've seen are just engines with the extras. How to keep that engine working or workable until reality shows finally bite it?
..to preserve for long term storage you need to drain the oil and fill the oil filter with 10 weight oil...the same oil used to preserve the fuel system by pushing/filling all the lines....place the engine in a large bag with desiccant bags and vacuum seal the bag...place some moisture indicators outside the bag and monitor every few months...
Well, it's finally that time, and it came way too soon. I'm left with the decision in the next week or two to buy or turn the lease in. Residual is a little over 10k which seems to be at or below market value for a 2016 Passion with 25k miles and in perfect condition. I have a $395 turn in fee...
I have the staggered setup with continental winter tires on the cute steel wheels.
I'm considering just buying 4 tires so I can rotate them and not have to worry about front vs back wearing out sooner than each other.
Is there any catch for doing this with winter wheels like traction control...
I just got a new 2018 453 Smart ForTwo coupe. Neat car.
I'm now trying to figure out whether it's possible to hardwire a radar detector and, if so, how. The detector I have is a Radenso Pro M, and I'd like to mount it to the windshield with the windshield mount that came with it.
