1st off - Be nice, it's his car - he can do what he wants with it.
2nd off - Maybe, but sometimes you buy a less expensive car initially to save money and then upgrade it as you get more funds.
3rd - Actually - probably not - According to Edmunds with minimum options:
S in Ingot Silver - MSRP $17,295
SE in Ingot Silver with Sport Package (which you had to have to order those rims) and Rims - MSRP $19,685.
Fog Light Mod - Roughly $150-175 in parts - more if you figure his time into it (and the switch that didn't work).
Rims - $640 at hubcaphaven
Leaves $1575 for tires, but he could have done better if he bought a wheel/tire package from a member and if he got someone to buy back the stock S tires and hubcaps. (OTOH - I'm neglecting the other upgrades you get with the SE Sport over the S, but ...)
