its not always the car that runs up front!
the best car with a rookie (newbie to racing period) will usually take a year(or more) to get up to speed.
no matter how good your car is it wont win until you can get it there, thats how people get turned off - they dont see progress. if you expect to run up front in 3-4 races its just not going to happen .. better to start with a slow car get it to go as fast as it can then slowly move up. you need to learn to race before you get HP..
