Tough question for me. When I think back about the cars and trucks I've owned, most are memorable: As the worst vehicle I've owned.
I'm not adverse to things. I love boats, even houses (old especially), and become more emotionally attached than I think is normal.
In fact, my worst vehicle may be our present family car. A typical 4 door jeep SUV. We bought it slightly used, less than 10k miles. It's 8 years old and now has about 75K easy road miles.
We took it in for routine inspection. We've put the usual $$ into it over the years, keep up with maintenance, religious with oil changes at the Promto-whatever. Write the checks,...
It's shot. Done! 8 years old, 75k miles, looks almost like new. A trusted mechanic (we've only used the same outfit for decades-we're loyal customers) took my wife under the lift and poked his finger through the frame in several places. Total death trap.
Did I mention it's 8 years old, 75k miles,....?
Amazingly, our mechanic did some research and there must have so many complaints that they extended the warranty. Which they should - Jeep built such a piece junk to start, used junk steel (according to our mechanic).
Naah,... this wasn't a build (I'm a builder - this car is an insult to builders!), this was a robbery for shareholders with what is charged for cars these days.
It will still cost 12-1500 in related parts but I feel like I won the lottery in my experience with, 'cars'.
