Here's my take. I own a 2008 2.5 with the 5 speed, it's been known to be the most reliable combo. Mine is the SE model with the leatherette, heated mirrors, seats, and washer nozzles, along with the upgraded 10 speaker audio system with satellite. 2008 (or 07) upgraded the engine from 150hp to 170hp, also VW updated the chain (in 07?) from the problem prone 05.5-06 chain stretching. Knock on wood, my car with 60,500ish miles has been rock solid. Only items replaced so far are normal wear items such as a battery, filters, wiper blades, etc. Vacuum pumps are prone to leaking (alas, mine is seeping) on the 2.5 models. Don't let them sell you a new pump though, all you need is a new seal. Since it's a manual its fairly easy to access. There are guys that have over 200K on their 2.5 without much done, and some have done a good bit. Luck of the draw. It is an excellent driving car, it excels on the highway. I netted 33-34mpg on our trip to Maryland and back. It is really fun to drive, especially with the 5 speed. Don't expect to win any races, but the 5 cylinder has good power. Its torque is down low, so it exhaust itself at around 5K. That said most will agree the 2008 and above are solid cars.
Now, VW is not for everybody. They are quirky cars indeed; it takes some getting used to. I would take it on a good 1/2 hour drive atleast to feel it out.
