Hi Andy, and welcome
There really is no way to quantify what it takes to build a PT car here...We have everything from low-buck cars (under 10K) to big buck cars (over 100K)....Best advice, build within your means, build what makes YOU happy, and most importantly...get out and DRIVE it

Although, after getting a small taste of what your gas prices are like (I think we are still 1/2 of what you pay even at $3.00 a gallon here)..that is becoming more and more difficult for those on a budget....
