2015 Buick LaCrosse — Should You Buy One?
Typical asking price: $10,000–$15,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
A quiet, comfortable, big-riding sedan that delivers near-luxury calm for mainstream money. The 3.6L V6 is strong; the eAssist mild-hybrid four is more complex. Comfortable and cheap to buy, with GM's usual electrical and timing-related watch-items. A relaxed cruiser if the V6 timing chain and electronics check out.
