The Benz is one of those companies that is purely driven by Leases. I dont know of a single person that has ever opted to buy the car and keep it long term. They lose a ton of value the first few years and then you have to sell your kidneys to keep one running after the warranty is up. Yea you can buy an extended warranty, but then you're left with a terrible depreciated asset.
Yes they are refined overall, but mostly are status symbols. That C450 AMG is not an actual AMG car. True AMG cars are above 100k mark with hand built engines. Its just an offshoot without the substance.
For the money I would opt out for an M3, but only if AWD was offered. People paying for the C450 with that snazzy interior wont see a fraction of the extra money they opted for when its time to sell the car.
Personally Benz vehicles dont do anything for me - especially when they slap that afterthought of a tablet in the middle of the console.
