I'm an 18yo in a 66yo body, at least that is what SWMBO tells me
I know exactly what you mean. And, interestingly, the X factor never really goes away. We keep also keep our vehicles because we still like 'em. We drove the JGC Overland diesel and both loved it and we can't wait to order it.
I had a BMW 5 series that I owned for 15 years......loved it, cared for it, serviced it but, when I couldn't do major work on it any more, I traded it in and I felt terrible. Someone got a great car......
We looked for a replacement for it back in 2011 and finally went with a new Kia Optima EX. We looked at a lot of sedans but when we sat in the Kia and drove the car we both said, this is it - the X factor!
We are both retired and mainly use our vehicles for road trips. In 3 years and 36k miles, it's taken us a lot of great places and has been reliable as heck, gets great gas mileage and we've had zero issues/problems.
All I've done is change oil and filters on it. We still like it a LOT (it hasn't lost the X factor!) and it will be SWMBO's car when we get the Overland.
We are trading in her 2005 Subaru Forester LL Bean. Back in 2005 we were looking to replace our 1996 Audi A4q (a problem child!) and SWMBO instantly loved the Forester - again, the X factor. 9 years and 73k miles later, it's been as reliable as hell and only the sunroof not returning fully has been an issue (I just closed it and removed the wiring from the switch!
The Subie has taken us some great places, towed our BMW R1150RT on a Kendon trailer over the Sierra's and Rockies and has been the great little Swiss Army Knife that we needed. We both feel bad about trading the Subie as there is really nothing wrong with it at all. However, even more than the Subie, the JGC will take us everywhere we want to go (more difficult National Park/State Park trails etc) and will trailer the bike (and not even notice it!) plus we now have the option of getting a travel trailer. And, finally, the JGC diesel will actually get us better mileage than the Subie on the highway!
We are fortunate that in our 36 years of marriage, we have a "vulcan mind meld" when it comes to buying auto's and we both recognize that "X" factor
We hope that our JGC will prove to be as great a vehicle as those mentioned above.
