I adore everything about my Volvo but the price it takes to keep it. Even the dealer admitted it is a lemon. Another reviewer hit the nail when he said "very good or awful." I got the short end of the stick on this one with weird problems (unraveling muffler gumming up exhaust, unexplained smokes inside and out...) and so may trips to the dealer, I know all the service people's kids' names. That being said, I love the way it drives, looks, feels and physically holds up, structure wise, I just picked a lemon. Would buy another one but can't gamble on picking a winner.
Style, driving and brand.
I don't think there is any way to detect a lemon, even within the dealer. Don't buy a brand like Volvo that's been returned quickly, unless it's coming off a lease. People choose Volvos and stick with them unless they're unloading a loser. That's my theory, anyway.
