I chose the Passat wagon over the A6 wagon, because the Passat's ride is superior and it has more interior space. In an attempt to protect myself against the VW's poor reliability reputation, I bought a certified pre-owned Passat *and* an extended warranty. Looking back, that was a smart move. However, now that all the warranties have expired, the Passat is breaking down with a vengeance. Every visit to the mechanic costs an arm and a leg, with the most recent visit (alternator + battery) costing me $1500! And it is only March! I am sad the Passat and I have to part ways now, because it is truly a safe and comfortable car. But I love my wallet more.
