if you buy from a dealership you are going to lose alot of money.. you're better off buying used, its cheaper and you wont lose as much money in depreciation or value of the car when it comes time to sell it
get her a service/tune up or do it yourself, change the spark plugs, change the oil, change the air breathers, check the pressure in your tyres, get braided hoses for your front brakes, get bigger tyres, lower it, get some injector cleaner, get some stuff you can put in the petrol/gas tank to...
