First, Thank you Gord&Fran for the shout out. Now for a few basics to follow when picking a shop:
#1 Never, repeat NEVER give a shop money up front. If they have to work off your money then they will work till it's drained and quit. Remember they have YOUR RIDE for collateral while all you have is their word which may or may not be worth something.
#2 Make a WRITTEN request about what is expected and an approximate cost which is subject to modification if modifications are made to the original plan.
#3 Get an estimated completion date but remember old rides can have part acquisition glitches so be flexible by months BUT NOT years.
#4 Follow Otto's advice on contacting at least 3 or 4 others that have had work done and treat this as Biblical as it is real world and not online gossip.
The above is how we operate and it must have merit because there is a 2 year waiting list to get in the door while dozens of "get the money" shops have gone belly up in the same 40 year period.
