Sounds like your parts person ran a VIN check - I've had this done also to confirm that the car I was paying for had the right options... if it says your Production Date is 2008-04-04 then your car is a 2008 build.

Now I don't think this applies in your case but there is a difference between Build date and Compliance date. For example, mine has a production date of Dec 02 2009 - so it is a 2009 build BUT it was complianced in Feb 2010, so some dealers would try to say that they are selling me a 2010 car. However, when it comes time to sell, buyers/dealer will go by the Build date when valuing that car.

My dealer first told me the car he was selling me was a 2010 vehicle, but I did my research and asked the question, and eventually got the whole truth - my car is a 2009 build, but it is a 2010 model (because it has the HDD nav, new iDrive and TopView camera). Although it was 2009 build, it did have the 2010 features, and I needed a car quickly so I took the deal.

Your car will have a Build plate (pop the engine hood open - on mine its in top left corner somewhere) that will confirm the Build date. It will also have a compliance plate (mine is on the door jamb of front passenger side), which will tell you the compliance date.
