2018 Jeep Wrangler Unlimited (JL) — Should You Buy One?

Kestrel Take

The redesigned JL Wrangler is a big step up — more refined on-road, better interior, still hugely capable off-road, and it holds value even better than the JK. Early JLs had some teething issues (electronics, a 'death wobble' concern) and the same removable-top leaks. As always, condition and abuse history rule. A clean, stock JL is an icon that barely depreciates.
