I'm looking at two different GTI's right now. Both cars look good. One is an 06 with 54,000 miles, and the other is an 08 with 79,000 miles. Both have manual transmissions. I asked the dealer I spoke with on the phone, and he said he thinks the 08 is a TSI, but isn't sure. Which car would be the better pick? Are there any advantages to getting a later model FSI compared to an early model? And if the 08 is a TSI, is the increased mileage worth it? Thanks in advance.
