Jr., those cars a so nice, I hope the owners actually drive them more then let them sit. Parts prices have been going up for several years as you noted, the suppliers are going away or are being consumed by group investors and that doesn't always do well for a hobby such as ours.
Hey there Junior, $125/hr shop rate is cheap for a specialty shop like yours. I think general mechanics shops in most places charge about that or more. Interesting summary of the $20k job. It will be interesting to see the before and after. Take care, Dan
