I'll name Volkswagens for one.
Even those '99 model Jettas still look relevant today as long as they've been kept decently.
Not mercedes... shyt looks old in 5 years
Cars with fewer lines age better. Also depends on how long they go before remodeling.
BMW's basically held the same look throughout their entire line for the whole of the 90's and into the early 00's.
I'd imagine the same will happen with current Audi's. They've got a uniform look throughout their line and as it's a big hit I'd be shocked to see it change anytime soon.
It seems like every new model Mercedes makes the last look like trash. I would only lease a Mercedes because you know it's gonna be ugly in 5 years.
