2018 Mercedes-AMG GT — Should You Buy One?
Typical asking price: $75,000–$105,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
A front-mid-engine V8 GT with supercar presence and a monstrous twin-turbo AMG V8 — the AMG GT is a genuine 911 Turbo rival with drama to spare. It's expensive to run and service, and abuse/track history matters. A documented, stock, un-tracked AMG GT with full history is a spectacular, usable exotic; verify the twin-turbo V8, transaxle, and electronics, and budget for premium AMG service and consumables.
