build it up very slowely. it is good that she goes in there happily.
start off with her in the back with the boot open and you with her. turn the engine on and give her a stuffed kong or bone to chew on to take her mind off it.
leave the engine on for 30 secs then turn it off and take her back into the house.
repeat a few times each day and gradually increase the time the engine is on for.
then start to close the boot without you there and increase the time she is alloun for slowly.
once she is happy to be in the car with the door closed and the engine on you can then move to driving.
i would litterally move the car out of the parking space (make sure you can get out forwards to start) and then put it back into another space (forwards) a little way up your road. i would always start in one direction as the back and forth can worry them a bit.
do this several times a day until she is completly happy and then gradually start going a bit further in the car each time.
once she is really happy at going round corners and etc start to park with her in the car.
remember take it slowly and if she gets worried then just take it back a step next time she gets in the car
good luck
oh and give her something to do whilst in the car like a stuffed kong or bone each time
