And don't buy into that traction control hype. It'll sometimes get you rolling when you otherwise wouldn't go, but it adds nothing, working strictly by subtraction. Traction control puts the brakes on a spinning wheel, intending to divert power to the non-spinning wheel. But VW considers itself a Mercedes wannabe and charges such prices. Just waiting for test models to become available, which is months away because the vehicle isn't imminent.
Many people have good luck doing that.
They get regular maintenance and cleaning and, as you say, aren't very old. But I doubt I'd buy one. Think how you use things that aren't yours. Most people don't treat them with the same respect as items they own. I'd always worry that there was some hidden, time-bomb issue lurking.
