Around $300 so far to fix CEL issue. About $50 for replacement bulbs (PRNDL light, radio LCD light, and trunk light) and cosmetic parts. About to spend some more to get HUD added to my car. Still need to repair paint in a few spots, a good washing and waxing to last me the rest of the year, and hood decal if I go for it.
Edit forgot to mention I've had this car for about 3 weeks.
