going fast is always fun but when you can't stop in time or control it.... it's not!!
Maybe look at handling and stopping first, wheels with some good tyres seeing as there the only bit that has contact with the road?!
The idea of selling the car and combining the money for an upgraded model is a good idea too, well cared for cars with a full detailed history are always more desirable. i was fortunate enough to get mine with a tonne of upgrades already done, i'd never be able to get a car and do whats been done to it for the amount i paid..... on the flip side its very satisfying modding it yourself!
whatever you choose there'll be loads of advice from people on here to help you out!
