I was informed since it's considered a "luxury" car, I had to get the synthetic oil which costs much more than the regular oil.

Look in your owners manual and see if synthetic oil is either recommended or mandated. if it is not mandated use the recommended weight (ie. 5W-30 or what ever) regular mineral oil is recommended

Being luxury car or not has nothing to do with which oil is recommended.
On your car I strongly recommend to use synthetic because of different reasons, one of them is having a turbo, which runs extremely hot and uses the engine oil. Synthetic oils resist heath on a higher level - also flows and lubricates a lot better in cold temperatures. The other thing is, these engines are bad to build up sludge, clogs breather valves. Good synth. oils has additives to prevent sludge build-up.
Use good synthetic, like Mobil 1 and replace it at no more than 5000 miles if you want to save money on the long term, otherwise you will replace turbo, breather valve, de-sludge engine, etc...
