Buy something

Hi Joe:

I'd like to tell you a story about my shop experience.

I went to a high end district in GZ for buying a luxury car/to buy a luxury car [of a luxury brand] while I was studying at university. I looked like a common/an ordinary student, so the staff didn't really want to serve me. That was embarrassing!  I ended up buying an expensive car from another [store]/concern/outlet/showroom to prove I could!  But I felt better when I had 'slapped their face' * by with money.

Don't be jealous of me.

How many students in China can afford to buy a luxury car ?
