I have always said that primary transportation should not be "messed" with. I have several young kids that stop by my shop regularly.
They all drive cars that have stock drive train, but they never fail to attempt a neutral or reverse drop when leaving.
I guess I`m supposed to be impressed that Mommy/Daddy or Grandma could afford to buy them a such an "AWSOME" car that is capable of squealing the tires when you dump the clutch at 5G`s.
When their cars screw up on them, it`s always the same story."I wasn`t running it hard today" Yea, but what about every other day for the last six months.
My suggestion would be to buy a good used transmission, get some buddys together and swap it yourself. your dad might appreciate that you a willing to work to save some $$ on the repair shop bill.
Once the car is fixed, I suggest driving it like you have a cop in the car with you. it will cost you much less in the long run for repairs and maintanance, and the extra cash can be used for your Z.
BTW, I can`t understand the mindset of kids that expect someone to buy them a car. This isn`t directed specifically toward anyone here, just the youth of today in general.
First they want a car, then they need gas money. Once the car starts to show some wear, they want somthing different.
Just like your drivers licence, it`s not a right, it`s a privalidge.
