Well
Some time ago I have been with my skyline at the mechanic.
Because at that time (just bought it) I wanted to check it out on a dyno + tune it.
The verbal agreement for the price was $140.00. After the work was done an invoice was handed to me. Total $220.00 and I was not prepared for that. I gave them $180.00 all I had on me and was told that I can pay the rest at the later time.
Why such a different price?
Few months on and I still did not pay the outstanding amount.
Sometime I really dont know where the prices are taken from.
I'm not going to give the name out mainly because it is a very highly recommended workshop on this forum. (not BMT)
It pisses me off when they do not really know how much to take from you.
I truly believe that They will take as much as you wiling to give. but at the same time not to much because this can deter you (customer) from comming again.
The best possible solution is do it yourself if you can or PAY UP.
